Interstate 410

 

Interstate 410 San Antonio Map - Interstate-Guide

The Interstate 410 beltway is well entrenched into the city limits of San Antonio.

Routing

Interstate 410/Connally Loop is a complete beltway around San Antonio, Texas, excepting a segment that runs concurrent with Interstate 35 in the northeast quadrant. Texas 16 merges with Interstate 410 for most of its western half. The state highway consists of a lengthy north-south route from Zapata on the Rio Grande north to U.S. 281 near Antelope, just south of Wichita Falls. The mileage statistics below do not factor in the Interstate 35 overlap. This explains why the Interstate 35 junction south of the city is signed as Exit 53 instead of Exit 49.

A stark contrast can be drawn when comparing the northern half of the beltway from U.S. 90 near Lackland A.F.B. to the Interstate 35 overlap with that of the southern half. The San Antonio metropolitan area sees most of the suburban growth towards the northwest and northeast, following the Interstate 10, U.S. 281, and Interstate 35 corridors. Compare that with anywhere south of U.S. 90 or Interstate 10 near Kirby, and Interstate 410 is paradoxical. The segment between Interstate 10 and U.S. 281 sees reconstruction at the present time, widening a narrow, six-lane, below-grade freeway to more modern standards. The frontage itself is heavily developed. Shift to the southside of the metropolitan area and one will encounter open space, frontage roads, a 70 mph speed limit, and only four lanes of travel. The highway actually encounters several vistas of the hill country to the south.

History

Interstate 410 around San Antonio was constructed through the 1950s and 1960s, with the first section of the beltway opening in 1958.1

Highway Guides

Zero Milepost - Interstate 35 - San Antonio, Texas
Perspective from Interstate 410 east
The first interchange of the Interstate 410 rotation is Exit 2/Texas Farm to Market Road 2536 - Old Pearsall Road. Exit numbers count down to zero in the counter-clockwise direction and Exit 53 represents what would also be considered Exit 0. Photo taken by Chris Patriarca (06/24/03).
0.75 mile guide sign for Exit 53/Interstate 35 on Interstate 410 east. Similar to the east parent junction, the Interstate 35/410 cloverleaf interchange includes collector/distributor roadways. Photo taken by Chris Patriarca (06/24/03).
Exit 53 sign for the upcoming approach to the eastbound c/d roadway. Interstate 35 is formally named the Pan Am Expressway throughout the San Antonio metropolitan area. Photo taken by Chris Patriarca (06/24/03).
This sign bridge at the Exit 53 c/d roadway divergence reveals that Texas 16 is overlapped with Interstate 410. The state route enters the beltway at Exit 13 and continues east to Exit 49. From there Texas 16 travels due south to an eventual terminus at Zapata near the Rio Grande. Photo taken by Chris Patriarca (06/24/03).
As is the case with the east parent junction, the individual ramps to Interstate 35 are not assigned suffixes. This eastbound photo shows the southbound Interstate 35 ramp as seen from the Interstate 410 east/Texas 16 south mainline. Photo taken by Chris Patriarca (06/24/03).
Milepost 0 can be found posted underneath the Interstate 35 overpasses between the mainline and collector/distributor roadways of Interstate 410 east. Photo taken by Chris Patriarca (06/24/03).
Perspective from Interstate 410 west
Interstate 410 westbound, one mile from the Exit 53 cloverleaf interchange at Exit 51/Texas Farm to Market Road 2790. Notice the rural character that Interstate 410/Texas 16 entails throughout the vicinity of the zero milepost interchange. Photo taken by Chris Patriarca (06/24/03).
The Interstate 35 cloverleaf interchange comes into view on Interstate 410/Texas 16 west/north. Photo taken by Chris Patriarca (06/24/03).
Interstate 410 switches orientation from east-west to north-south at the Interstate 35/Exit 53 c/d roadway. Ten miles to the northeast is downtown San Antonio. Photo taken by Chris Patriarca (06/24/03).
Continuing on the Interstate 410 westbound collector-distributor roadway for Interstate 35. Photo taken by Chris Patriarca (06/24/03).
Perspective from Interstate 35 north
1.50 miles to the southwest of the beltway, the first guide sign for the Interstate 410/Texas 16 overlap (Exit 145A). Photo taken by Chris Patriarca (06/24/03).
Hazardous Materials advisory sign for traffic on Interstate 35 mandating a departure to Interstate 410 to bypass the central business district of San Antonio. Photo taken by Chris Patriarca (06/24/03).
A rather nondescript guide sign for Exit 145A, one half mile south of the San Antonio beltway. Photo taken by Chris Patriarca (06/24/03).
Connally Loop guide sign of Interstate 410 on Interstate 35 northbound. Photo taken by Chris Patriarca (06/24/03).
This auxiliary guide sign advises motorists of the pending split of the collector/distributor roadway for Interstate 410/Texas 16. This Interstate junction of Interstate 410 is the least busy of them all. Photo taken by Chris Patriarca (06/24/03).
Button copy guide signs remain in place at the Exit 145A c/d roadway departure. This sign bridge gives the first indication of Exit 145B of Texas Loop 353. The paralleling state route represents the original U.S. 81 alignment in southwest San Antonio. Photo taken by Chris Patriarca (06/24/03).
Additional button copy signs at the Interstate 410 east/Texas 16 southbound ramp from Interstate 35 north. Traffic utilizing that ramp will reach the Interstate 37 junction in 12 miles. Photo taken by Chris Patriarca (06/24/03).
Perspective from Interstate 35 south
Traveling southwest on Interstate 35 at the two mile guide sign of Exit 145A - Interstate 410/Texas 16. Photo taken by Chris Patriarca (06/24/03).
Original button copy signs (with reflective shields) southbound at Exit 145A for Texas Loop 383 north (original U.S. 81). The pull-through panel reveals the imprint from the removed U.S. 81 shield. For the most part U.S. 81 was overlapped with Interstate 35 from the present terminus in north Texas southward through Laredo. Because of this concurrent routing, all of U.S. 81 was truncated south of the lengthy overlap. This routing change occurred by the early 1990s. Photo taken by Chris Patriarca (06/24/03).
The Texas Loop 383 on-ramp becomes an exit-only lane for the collector/distributor roadway of Exit 145A/Interstate 410 and Texas 16. Photo taken by Chris Patriarca (06/24/03).
Button copy signs at the Interstate 410/Texas 16 northbound ramp. This sign bridge still retains its lighting fixtures, an increasingly rare sight in the metro area of San Antonio. Photo taken by Chris Patriarca (06/24/03).
Interstate 410 east/Texas 16 southbound cloverleaf ramp. Traffic that does not take this ramp can return to Interstate 35. 140 miles to the south is the control city of Laredo. Photo taken by Chris Patriarca (06/24/03).
Western Parent Junction - Interstate 10 - Balcones Heights, San Antonio, Texas
Perspective from Interstate 410 east
Interstate 410 east as it nears the western parent junction with Interstate 10 and U.S. 87. Due to the interchange redesign project, this and the next guide sign are temporary. Decorative concrete sign bridge supports featuring the Lone Star motif are already in place for the eventual overhead assemblies. Photo taken by Chris Patriarca (06/24/03).
Still a fair distance out from the interchange, traffic to Interstate 10/U.S. 87 departs. The current configuration sees a short ramp on the ground to Interstate 10/U.S. 87 east/south. This will change with the construction of a new flyover ramp to facilitate the same direction. Photo taken by Chris Patriarca (06/24/03).
This set of guide signs reveals the Exit 16B/A numbers applied to the west parent junction. San Angelo is featured as a second control city for the westbound Interstate 10 ramp. This is for the overlapped U.S. 87 which ultimately travels to the west-Texas city of 88,439. The two routes split at Interstate 10 Exit 523, 41 miles to the west. Photo taken by Chris Patriarca (06/24/03).
Continuing on the Exit 16B flyover to Interstate 10 west/U.S. 87 north. The yet to be completed flyover to Interstate 10 east/U.S. 87 south will eventually depart from this section of Exit 16. Photo taken by Chris Patriarca (06/24/03).
A look at the partially completed stack interchange of Interstate 10/410/U.S. 87. The original ramps between the two highways are kept open until their replacements are completed. Visible in this scene is the stub ramp that will eventually carry Interstate 10 west/U.S. 87 north traffic to Interstate 410 west (visible to the left). Photo taken by Chris Patriarca (06/24/03).
At the future split of Exit 16B/A on the Interstate 410 flyover ramp to Interstate 10 west/U.S. 87 north. The control city of I-10 is El Paso. The longest distance along the transcontinental route between control cities is El Paso to San Antonio, a lengthy 556 miles. Photo taken by Chris Patriarca (06/24/03).
Reassurance sign bridge on the Interstate 10 west/U.S. 87 northbound ramp. Although not a factor in the west parent junction, Texas Loop 345, situated to the west of Interstate 10 at this point, represents the original U.S. 87 through northwest San Antonio. The former federal highway represents the first interchange Interstate 410 encounters to the southwest of Interstate 10. Photo taken by Chris Patriarca (06/24/03).
Merging onto Interstate 10 west/U.S. 87 north. The barricaded shoulder will eventually bring Interstate 410 westbound traffic onto the same connection to Interstate 10 west. Photo taken by Chris Patriarca (06/24/03).
Perspective from Interstate 410 west
The heavily traveled Interstate 410 as it nears the west parent junction at Exit 16A/B. Most of Interstate 410 between Interstate 10/U.S. 87 and San Antonio International Airport is depressed below the built up areas nearby. Photo taken by Chris Patriarca (06/24/03).
One half mile east of the Interstate 10/410/U.S. 87 stack interchange. Many sign bridges along the freeway system of the city of San Antonio feature lane control signals such as these that can be adjusted depending on traffic conditions. Photo taken by Chris Patriarca (06/24/03).
Entering the stack interchange of Interstate 10/U.S. 87. The current configuration sees a left-hand off-ramp for traffic returning to downtown via I-10 east. This ramp will be eliminated and replaced with a flyover departing from the right. Photo taken by Chris Patriarca (06/24/03).
An original Exit 16A - Interstate 10 east/U.S. 87 southbound guide sign sits amid the chaos of construction and heavy traffic along Interstate 410 westbound. Photo taken by Chris Patriarca (06/24/03).
About to pass underneath Interstate 10, the eastbound ramp departs via Exit 16A. Situated nearby is Texas Loop 345/Fredericksburg Road, a northwest to southeast arterial between central San Antonio and Balcones Heights. Photo taken by Chris Patriarca (06/24/03).
Perspective from Interstate 10 west
2.25 mile advance button copy signage for Interstate 410/Exits 564B/A on Interstate 10 westbound. Note that the cardinal direction of "EAST" is removed from the sign panel as will be the case with signage at the interchange itself. Photo taken by Alex Nitzman/Andy Field (12/31/02).
One button copy sign of Interstate 410/Exit 564 remains due to construction as Interstate 10 westbound/U.S. 87 northbound pass by Exit 565A/Crossroads Boulevard. This exit serves the Balcone Heights community. Photo taken by Alex Nitzman/Andy Field (12/31/02).
Interstate 410 Connally Loop guide signage 0.25 miles south of Exit 564B of Interstate 10 west/U.S. 87 north. The beltway is named after a former Texas congressman. Photo taken by Alex Nitzman/Andy Field (12/31/02).
Button copy signage for Interstate 410/Exits 564B/A on Interstate 10 eastbound. Just above the Interstate 410 Texas shield is an imprint from the word "EAST". An Interstate 410 West panel must have been displayed to the left on the now empty brackets. Photo taken by Alex Nitzman/Andy Field (12/31/02).
Original signage with replaced shields on Interstate 10 as it enters the Exit 564 interchange. These signs are doomed for the scrap pile as both of the ramps Pictured will be replaced upon completion of a new stack interchange. Photo taken by Alex Nitzman/Andy Field (12/31/02).
New signage is in place for Exit 564A to Interstate 410 eastbound on Interstate 10 westbound. This otherwise substandard ramp is in the process of being replaced with a high speed fly-over just to the south. There are no control cities used for Interstate 410 signage from Interstate 10 in San Antonio. Photo taken by Alex Nitzman/Andy Field (12/31/02).
Perspective from Interstate 10 east
Four lanes of Interstate 10 sink southeastward toward downtown San Antonio at Exit 562/Medical Drive. Interstate 410 is 1.50 miles to the east. Medical Drive derives its name from its connection to South Texas Medical Center. Photo taken by Chris Patriarca (06/24/03).
Now one mile to the northwest of Exit 564/Interstate 410 on Interstate 10 east. Houston now debuts as a second control city for Interstate 10 eastbound. Photo taken by Chris Patriarca (06/24/03).
A future six lane Interstate 10 continues toward Interstate 410/Exit 564. Guide signs now begin to direct motorists for the upcoming stack interchange with the Connally Loop. Photo taken by Chris Patriarca (06/24/03).
Interstate 10 again depressed below the surrounding landscape. Interstate 410 is allocated two exit-only lanes as the mainline of Interstate 10 draws to within one half mile of Exit 564. Photo taken by Chris Patriarca (06/24/03).
The split of Exit 564/Interstate 410 exit ramps from Interstate 10 east. This decorative sign bridge features the architectural theme of the rebuilt interchange's new flyover ramps. Photo taken by Chris Patriarca (06/24/03).
Rising high above the Interstate 10 below, Exit 564 prepares to partition into the respective Interstate 410 ramps. All hazardous materials based cargo must utilized the beltway to avoid the central business district of San Antonio. Photo taken by Chris Patriarca (06/24/03).
Exit 564 ramp split for Interstate 410. San Antonio International Airport is five miles to the east and is represented by the small airplane sign on the left-hand panel. Photo taken by Chris Patriarca (06/24/03).
Eastern Parent Junction - Interstate 10 - Kirby, Texas
Perspective from Interstate 410 south
Just beyond the split of Interstate 410 from Interstate 35 on southbound. 0.75 miles separate the sign bridge from the east parent junction. Meanwhile Exit 32 for Dietrich Road is situated one fourth of a mile ahead. Interstate 410 northbound does not see access to Dietrich Road, but instead sees an off-ramp for Texas Farm to Market Road 76 and Kirby. Photo taken by Chris Patriarca (06/24/03).
Like many of the off-ramps on the Texas Interstate system, Exit 32 on Interstate 410 southbound consists of a simple slip ramp between the mainline and the associated frontage road. Traffic to Interstate 10/U.S. 90 is now directed to the right-hand lane. Photo taken by Chris Patriarca (06/24/03).
Interstate 410 southbound features a collector/distributor roadway for access to Interstate 10/Exit 33 in either direction. This photograph looks southbound on Interstate 410 at the beginning of the said roadway. This junction is just two miles south of the Interstate 35 overlap in northeast San Antonio. Top photo taken by Alex Nitzman/Andy Field (12/30/02); bottom photo taken by Chris Patriarca (06/24/03).
Continuing on the c/d roadway to the Interstate 10/U.S. 90 westbound ramp into downtown San Antonio. Interstate 10 and U.S. 90 intermingle quite often between San Antonio and the Louisiana state line. For traffic heading eastward to Houston, open meadows and pastures await along the 150+ mile journey. Top photo taken by Alex Nitzman/Andy Field (12/30/02); bottom photo taken by Chris Patriarca (06/24/03).
Interstate 10/U.S. 90 eastbound cloverleaf and the c/d roadway return to Interstate 410 south. Photo taken by Chris Patriarca (06/24/03).
Perspective from Interstate 410 north
The first mentioning of the Interstate 10/U.S. 90 interchange on Interstate 410 northbound is 2.50 miles to the south at the U.S. 87/Rigsby Avenue interchange (Exit 35). U.S. 87 departs Interstate 10 three miles to the east before intersecting the San Antonio beltway. The highway is an important route between the city and Cuero, Victoria, and Port Lavaca to the east and south. Photo taken by Chris Patriarca (06/24/03).
Interstate 410 maintains its greenery as it encounters Exit 34, Texas Farm to Market Road 1346/East Houston Street. This east-west highway travels from Gardendale to the east into downtown San Antonio. Photo taken by Chris Patriarca (06/24/03).
0.25 mile guide sign for Exit 33/Interstate 10/U.S. 90. A collector/distributor roadway is in place for this direction of the west parent junction as well. Photo taken by Chris Patriarca (06/24/03).
Interstate 410 north at the Exit 33 c/d roadway departure. Interstate 410 maintains just four lanes throughout the southeast quadrant of the beltway routing. Traffic increases however, as Interstate 410 continues north toward Kirby and Windcrest. Photo taken by Chris Patriarca (06/24/03).
Interstate 10/U.S. 90 eastbound ramp from Interstate 410 north. A rapid departure of the metropolitan area is afforded to eastward travelers as the Interstate 10 corridor is still vastly rural. Photo taken by Chris Patriarca (06/24/03).
Interstate 10 and U.S. 90 westbound cloverleaf ramp (Exit 33B). The east-west route merges with Interstate 35 nine miles to the west for a short overlap near downtown. Interstate 10 between Exits 572 and 577 represent the lowest latitude that the transcontinental freeway encounters on its 2,460.34 routing. Photo taken by Chris Patriarca (06/24/03).
Perspective from Interstate 10 east
Two miles west of Interstate 410 on Interstate 10 eastbound at Exit 579/Houston Street. Houston Street in conjunction with Commerce Street once carried U.S. 90 from east San Antonio and Kirby into Downtown San Antonio. The federal route is relegated to an Interstate overlap with I-10 from well east of the metropolitan area into downtown. Photo taken by Chris Patriarca (06/24/03).
1.25 miles west of Interstate 410 on Interstate 10 eastbound. Ahead is Exit 580 for Texas Loop 13/W.W. White Road. Texas Loop 13 was part of a greater route before Interstate 410 came to town. The route truncated just two miles to the north because of the beltway and now serves local interests for the most part in this vicinity. Photo taken by Chris Patriarca (06/24/03).
Six lanes of Interstate 10 continue toward the east parent junction of Interstate 410 at Exit 580/Texas Loop 13. Texas Loop 13 concludes at the Interstate 35/410 overlap beginning just two miles to the north. Photo taken by Chris Patriarca (06/24/03).
Exit 581 guide sign proclaiming the formal name of Interstate 410 - Connally Loop. These signs can be found on both directions of Interstate 10 at both junctions with the beltway. Photo taken by Chris Patriarca (06/24/03).
The third eastbound lane of Interstate 410 becomes exit-only for Interstate 410/Exit 581. Interstate 10 carries at least six lanes from Interstate 37 eastward to the beltway, and only four lanes as it departs the metropolitan area. Photo taken by Chris Patriarca (06/24/03).
The split of the Exit 581 collector/distributor roadway from the Interstate 10 eastbound mainline. Ahead is Exit 582 for Ackerman Road and the suburb of Kirby. Note the dramatic difference between the Interstate 10 character and landscape of the eastern parent junction from that of the western of Interstate 410. Photo taken by Chris Patriarca (06/24/03).
The southbound Interstate 410 ramp departs from the eastbound c/d roadway. This junction of Interstate 10/410 is a standard cloverleaf. The first southbound interchange of Interstate 410 beyond this junction is Exit 34 for Gardendale. Photo taken by Chris Patriarca (06/24/03).
Northbound Interstate 410 cloverleaf ramp as the collector/distributor prepares to return to Interstate 10 east. To the north Interstate 410 merges with Interstate 35 in just two miles. Photo taken by Chris Patriarca (06/24/03).
Perspective from Interstate 10 west
Hazardous materials advisory sign on Interstate 10 westbound as it nears the Interstate 410 east parent junction. Hazmats are banned on all of Interstates 10, 35, and 37 within the San Antonio Beltway. Photo taken by Chris Patriarca (06/24/03).
Exit 581/Connally Loop sign on Interstate 10 west. Interstate 410 is the second of two beltways Interstate 10 encounters on its cross country journey. This will change to the third once Interstate 295 is completed to the east of Interstate 95 at Jacksonville, Florida. Photo taken by Chris Patriarca (06/24/03).
Button copy guide signs remain at the Exit 581 collector/distributor roadway departure from Interstate 10/U.S. 90 west. Downtown San Antonio is another five miles to the west. Interstate 410 will meet Interstate 35 20 miles to the southwest for traffic interests to the border city of Laredo. Photo taken by Chris Patriarca (06/24/03).
Northbound Interstate 410 exit ramp from the westbound c/d roadway. Again button copy signs are in place for westbound motorists. Note also the rarely used mileage unit of 2/10th of a mile for the southbound ramp. Photo taken by Chris Patriarca (06/24/03).
Southbound Interstate 410 cloverleaf ramp of Interstate 10 west. In the background is the one-fourth mile sign bridge of the Texas Loop 13 interchange. Photo taken by Chris Patriarca (06/24/03).
