Interstate 430 Arkansas

Routing

Interstate 430 provides a both a western bypass of Little Rock and a commuter route by joining Interstates 30 and 40. The bridge across the Arkansas River is the lone crossing of the waterway between Downtown Little Rock and Conway, some 25 miles to the northwest.

History

Interstate 430 was constructed initially from Markham Street in west Little Rock to Interstate 40 near Crystal Hill. The route was fully completed by 1976.

Exit 5 with Shackleford Road was not an original exit on Interstate 430; it was added sometime between 1982 to 1984. Interstate 430 is eight lanes wide between Exits 5 and 8 (Rodney Parham Road). The fourth lane in each direction was added when Exit 5 opened.1 However, through the Big Rock Interchange (junction of I-430 and I-630), Interstate 430 reduces to six through lanes, with collector distributor lanes facilitating movements to loop ramps with the I-630 c/d roadways between Chenal Parkway and Baptist Health Medical Center.

Interstate 430 southbound at the final mainline interchange Exit 1/Arkansas 5 - Stagecoach Road. Three lanes of Interstate 430 press southward for the final 1.25 miles to Exit 129A/B - Interstate 30. Photo taken by Chris Patriarca (05/03/03).
Interstate 430 reduces to two lanes as it nears the terminus interchange with Interstate 30. The exit numbering scheme utilizes Interstate 30 mileposts. This is a common practice in the Natural State. Photo taken by Chris Patriarca (05/03/03).
Interstate 30 ramp split at Exit 129A/B on Interstate 430 south. The overpass is that of the westbound frontage road of Interstate 30. Similar to Interstates in the state of Texas, Interstate 30 sees a frontage road system in southwest Little Rock through to Exit 135/West 65th Street. Photo taken by Chris Patriarca (05/03/03).
Perspective from Interstate 30 east
Interstate 30 eastbound near the Vimy Ridge overpass, one mile from the southern terminal interchange of Interstate 430. Construction squeezes four lanes of Interstate 30 through southwest Little Rock. Photo taken by Chris Patriarca (05/03/03).

Another view of the Exit 129/Interstate 430 eastbound departure from Interstate 30. The western bypass of Little Rock sees its first interchange with Arkansas 5 while encountering the western terminus of Interstate 630 at Exit 8. Photo taken by Chris Patriarca (05/03/03).

A closer look at the Interstate 430 gorepoint sign on Interstate 30 east at Exit 129. In the background is the one mile guide sign for Exit 130/Arkansas 338 - Baseline Road. Photo taken by Chris Patriarca (05/03/03).
Perspective from Interstate 30 west
Construction reduces Interstate 30 westbound to only one lane through the Interstate 430 southern terminal interchange. This photo shows the Exit 129 ramp departure for the West Little Rock bypass. Photo taken by Steve Hanudel (08/18/05).
Northern Terminus - Interstate 40 - North Little Rock/Maumelle, Arkansas
Perspective from Interstate 40 west
Original concrete bumps westbound motorists as they approach Exits 147 and 148 on Interstate 40 westbound. Arkansas 100, known as Crystal Hill Road, represents the next interchange. The state route also represents the first southbound interchange of Interstate 430, two miles to the southwest. Photo taken by Eric Stuve (12/19/02).
Westbound Interstate 40 at Exit 147, the last North Little Rock interchange. Arkansas 100 begins at this interchange and progresses northwest to Maumelle and a return to Interstate 40. Photo taken by Chris Patriarca (05/03/03).
A collector/distributor roadway exists between Arkansas 100 and Interstate 430. Therefore Exit 147 consists of a slip ramp from Interstate 40 to Interstate 430. The c/d roadway also facilitates merging traffic from Arkansas 100 to Interstate 40 as well. Photo taken by Eric Stuve (12/19/02).
An auxiliary guide sign is in place along the westbound collector/distributor roadway. This is the only sign for Interstate 430 to feature a control city. Photo taken by Chris Patriarca (05/03/03).
Interstate 430 southbound begin from the adjacent c/d roadway of Interstate 40 as the return flyover from northbound is seen above. The next Interstate 40/U.S. 65 interchange is five miles to the north at the town of Morgan. Photo taken by Chris Patriarca (05/03/03).
A view of the collector/distributor roadway ending from the Interstate 40 mainline. Traffic that does not enter onto Interstate 430 returns to Interstate 40 west. This lane is in place for Arkansas 100 traffic eminating from Exit 148. Photo taken by Eric Stuve (12/19/02).
Perspective from Interstate 40 east
Interstate 40 enters the Little Rock metropolitan area and sees the first sign for the upcoming Interstate 430 junction. Interstate 430 originally saw no control cities. New signs however now include Texarkana for the connection to Interstate 30. Photo taken by Chris Patriarca (05/03/03).
These overheads are situated just before the Exit 147 departure of Interstate 430 southbound from Interstate 40 east/U.S. 65 southbound. Interstate 430 actually enters the city limits of Little Rock in four miles, while U.S. 65 enters downtown in nine miles. Photo taken by Chris Patriarca (05/03/03).
The previous set of signs on the Exit 147 sign bridge Pictured in the above photograph. Note the smaller shield for Interstate 40 with the state name and the original sign lighting fixtures and supports. Also note the abandoned practice of centering exit tabs on the Interstate 430 panel. Vidcap taken 05/30/95.
A second guide sign advises motorists to Interstate 430 southbound at the actual ramp beginning. Interstate 430 southbound sees one North Little Rock exit with Arkansas 100 at Exit 12. South of that junction, the west bypass of the capital city crosses the Arkansas River into the city limits of Little Rock itself. Photo taken by Chris Patriarca (05/03/03).
This video capture shows the previous set of signs at the Exit 147 gorepoint along Interstate 40 east. Note that the old sign included an Exit 147 tab and that the Exit 148 guide sign in the background omitted Arkansas 100. Vidcap taken 05/30/95.
Perspective from Interstate 430 north
The last mainline interchange of Interstate 430 is Exit 12 at Arkansas 100. Interstate 430 maintains six lanes at this point but reduces to four as it approaches the terminus. The same configuration exists at the southern terminus. Photo taken by Chris Patriarca (05/03/03).
Unlike the southern terminus, Interstate 430 northbound uses its own exit numbering scheme for the Interstate 40 interchange. Instead of Interstate 40 mileposts delineating the exit numbers, Interstate 40 ramps are assigned Exit 13A and 13B. Photo taken by Chris Patriarca (05/03/03).
Original concrete of Interstate 430 concludes the freeway as traffic splits between Interstate 40 east and west. Interstate 40 westbound travels to Conway in 21 miles. Interstate 40 eastbound intersects the eastern terminal of Interstate 30 in six miles. Photo taken by Chris Patriarca (05/03/03).
