Interstate 182 Washington

 

Tri-Cities of Washington Map - Interstate-Guide

Interstate 182 serves the Tri-Cities area. The most recent population statistics for the three cities are: Kennewick - 55,780; Pasco - 33,010; Richland - 39,350; and West Richland - 8,735.

History

Opened in 1986, Interstate 182 serves the Tri-cities area of southeastern Washington. The highway spurs from Interstate 82 east into downtown Richland and Pasco, ending at U.S. 395 north. U.S. 12 overlaps with Interstate 182 for its entire duration.

Western Terminus - Interstate 82 - west of Richland, Washington
Perspective from Interstate 182/U.S. 12 West
Traveling west on Interstate 182 and U.S. 12, the pull through sign after Exit 4 (Junction Washington 240) shows Interstate 82 rather than Interstate 182. U.S. 12 is omitted from this overhead sign. Photo taken by AARoads (08/28/06).
Westbound Interstate 182 comes to an end as it splits into east and west Interstate 82. The left lane connects to Interstate 82 east (south) to Umatilla and Pendleton, while the right lane connects to Interstate 82 west to Yakima. U.S. 12 merges onto westbound Interstate 82. Photo taken by AARoads (08/28/06).
These roadside signs provide the same information as the overheads and again remind travelers of the lane allocations for east and west Interstate 82. Photo taken by AARoads (08/28/06).
Interstate 182 west comes to an end at this point, as the freeway divides into east and west Interstate 82. There is no END shield posted for Interstate 182. Use the right lane to continue west on U.S. 12 (and Interstate 82) to Yakima. Photo taken by AARoads (08/28/06).
Perspective from Interstate 82 West
The first signed connection from westbound (northbound) Interstate 82 to eastbound Interstate 182 is via Exit 113, Junction U.S. 395 north to Kennewick and Pasco. However, this is not the actual interchange with Interstate 182, which is at Exit 102. Photo taken by AARoads (08/28/06).
Use U.S. 395 north to Kennewick, Pasco, and Spokane via Interstate 90. Most of the route to Spokane is either freeway or expressway, with traffic signals only in Kennewick. A proposed Washington 397 extension south to Interstate 82/U.S. 395 may create an alternate route around downtown Kennewick for through traffic on U.S. 395. The interchange with Washington 397 (if built) would be south of the current U.S. 395 junction. Photo taken by AARoads (08/28/06).
Westbound (northbound) Interstate 82 reaches Exit 113, Junction U.S. 395 north to Interstate 182 east. The actual interchange between Interstate 82 and Interstate 182 is located at Exit 102; it is a trumpet interchange and offers a full connection in all directions. However, U.S. 395 cuts off some of the back-tracking. Interstate 182 serves Richland, Kennewick, and Pasco. Photo taken by AARoads (08/28/06).
After Exit 113, Junction U.S. 395 north, Interstate 82 west travels alone for ten miles, until it meets Interstate 182 and U.S. 12 at Exit 102. In between U.S. 395 and Interstate 182 are two exits: Exit 109, Badger Road/Clearwater Avenue, and Exit 104, Dallas Road. Photo taken by AARoads (08/28/06).
Westbound Interstate 82 approaches Exit 102, Junction Interstate 182/U.S. 12 east to Richland, Kennewick, and Pasco (together known as the Tri-Cities), one mile. Photo taken by AARoads (08/28/06).
For those traveling on U.S. 395 north to Spokane, use Interstate 182/U.S. 12 east to the U.S. 395 north exit in Pasco. Photo taken by AARoads (08/28/06).
Westbound Interstate 82 reaches Exit 102, Junction Interstate 182/U.S. 12 east to the Tri-Cities. Interstate 182 is a fairly long spur route, connecting Interstate 82 with all three cities on its path. It ends after the U.S. 395 north interchange prior to the Snake River crossing. Photo taken by AARoads (08/28/06).
Perspective from Interstate 82/U.S. 12 East
This mileage sign along eastbound Interstate 82 provides the distance to Exit 102, Junction Interstate 182/U.S. 12 east to the Tri-Cities. It also provides distance to Badger Road and U.S. 395 (but omits Dallas Road). Photo taken by AARoads (08/28/06).
The next exit along eastbound Interstate 82 and U.S. 12 is Exit 102, Junction Interstate 182/U.S. 12 east to the Tri-Cities. U.S. 12 and Interstate 82 part ways permanently at Exit 102, with U.S. 12 traveling through Richland and Pasco before shifting onto its own alignment en route to Walla Walla and Lewiston. Photo taken by AARoads (08/28/06).
Westbound Interstate 82 approaches Exit 102, Junction Interstate 182 and U.S. 12 east to Richland, Pasco, and Kennewick (via Washington 240). Photo taken by AARoads (08/28/06).
Eastbound Interstate 82 reaches Exit 102, Junction Interstate 182/U.S. 12 east to the Tri-Cities. Interstate 182 is a fairly long spur route, connecting Interstate 82 with all three cities via Interstate 182 and/or Washington 240. It ends after the U.S. 395 north interchange prior to the Snake River crossing. Photo taken by AARoads (08/28/06).
Perspective from Interstate 182/U.S. 12 West
Merging onto eastbound Interstate 182 and U.S. 12, traffic from westbound Interstate 82 (right lane) merges with traffic from eastbound Interstate 82 (left lane). Photo taken by AARoads (08/28/06).
This is the first shield on eastbound Interstate 182. It is a faded shield in a white box (not a cutout), and it does not have a companion U.S. 12 shield as it should. Photo taken by AARoads (08/28/06).
A mileage sign provides the distance to Junction Washington 240, Richland, and Pasco via eastbound Interstate 182 and U.S. 12. Photo taken by AARoads (08/28/06).
Eastern Terminus - Lewis Street - Pasco, Washington
Perspective from Interstate 182 and U.S. 12 East
Traveling east, Interstate 182 and U.S. 12 approach the junction with U.S. 395 south to Kennewick and Pendleton (Exit 12A). After this interchange, U.S. 395 will merge onto Interstate 182 east. Photo taken by AARoads (08/28/06).
Interstate 182 and U.S. 12 east split into a local/bypass configuration, with the right two lanes providing local access to Exit 12A, Junction U.S. 395 south to Kennewick and Pendleton and Exit 12B, N. 20th Avenue. These collector-distributor lanes will rejoin Interstate 182 after this interchange. Photo taken by AARoads (08/28/06).
After the collector-distributor lanes merge back together, a reassurance shield assembly for Interstate 182 and U.S. 12-395 is posted. U.S. 395 shares its alignment with Interstate 182 for a couple of miles, then splits to the north at Exit 14. Photo taken by AARoads (08/28/06).
Between the two U.S. 395 interchanges is Exit 13, North 4th Avenue, which serves the city center of Pasco via Old U.S. 12. Photo taken by AARoads (08/28/06).
The next exit along eastbound Interstate 182 and U.S. 12-395 is Exit 14, Junction U.S. 395 north to Spokane and Washington 397 south to Pasco and Kennewick. Photo taken by AARoads (08/28/06).
Eastbound Interstate 182/U.S. 12 split from northbound U.S. 395 at Exit 14. Again, Interstate 182 forms a dual freeway, with the left two lanes bypassing the interchange, and the right lane forming a collector-distributor lane. For now, the connection between Interstate 182 and U.S. 395 is not a direct freeway to freeway connection, but that could be upgraded in the future. Photo taken by AARoads (08/28/06).
The dual freeway allows for two through lanes and two local lanes to connect to Washington 397 south (Exit 14A) and U.S. 395 north (Exit 14B). Photo taken by AARoads (08/28/06).
At the ramp to northbound U.S. 395 (Exit 14B), a pull through sign shows only a U.S. 12 shield. The mileage sign shows the distance to Walla Walla and Lewiston, Idaho. Photo taken by AARoads (08/28/06).
As the dual freeway section comes to an end, U.S. 12 is signed alone on the collector-distributor lanes. However, Interstate 182 is still not finished. Photo taken by AARoads (08/28/06).
The next exit along eastbound is Lewis Street, followed by Kahlotus. Note that neither interchange has exit numbers; the end of Interstate 182 comes just before the Lewis Street interchange. Photo taken by AARoads (08/28/06).
Prior to the Lewis Street exit, Interstate 182 finally reaches its terminus. Its end is signed with an END shield below the U.S. 12 east reassurance shield. From here, U.S. 12 continues east to cross the Snake River to Burbank, travels southeast to connect with U.S. 730 near Wallula, then turns east again to serve Walla Walla. Through traffic to Lewiston should use Washington 124 as an alternative and thus avoid Walla Walla. Photo taken by AARoads (08/28/06).
After the END shield for Interstate 182, eastbound U.S. 12 reaches the Lewis Street exit. Photo taken by AARoads (08/28/06).
Perspective from U.S. 12 East
The next exit ramp serves Kahlotus. Photo taken by AARoads (08/28/06).
Now an expressway, the junction with A Street is an at-grade intersection rather than a freeway interchange. U.S. 12 continues east toward the Port of Pasco along the Snake River. Photo taken by AARoads (08/28/06).
Eastbound U.S. 12 reaches the intersection with A Street, which provides access to the Port of Pasco. Photo taken by AARoads (08/28/06).
A second at-grade intersection is at Tank Farm Road, which is the last intersection before U.S. 12 crosses the Snake River. Use Tank Farm Road south to Sacajawea State Park. Photo taken by AARoads (08/28/06).
After the Tank Farm Road intersection, U.S. 12 east prepares to cross the Snake River and then intersect with Washington 124 east to Waltsburg, Clarkston, and Lewiston. Photo taken by AARoads (08/28/06).
U.S. 12 uses the Vaughn Hubbard Bridge to cross the Snake River. Photos taken by AARoads (08/28/06).
After crossing the Vaughn Hubbard Bridge, U.S. 12 east meets Washington 124 at this traffic signal in Burbank. The expressway alignment of U.S. 12 continues as it angles southeast to follow the Columbia River's east bank toward Wallula via the McNary National Wildlife Refuge. However, the road reverts to two lanes before meeting U.S. 730 near Wallula. Photo taken by AARoads (08/28/06).
Perspective from U.S. 12 West
Changing directions, after the Washington 124 intersection, eastbound U.S. 12 prepares to cross the Snake River via the Vaughn Hubbard Bridge. Photo taken by AARoads (08/28/06).
After crossing the bridge, the first of two at-grade intersections before the Lewis Street intersection and beginning of Interstate 182 is with Tank Farm Road (to Sacajawea State Park). Photo taken by AARoads (08/28/06).
U.S. 12 uses the Vaughn Hubbard Bridge to cross the Snake River. The westbound lanes use the older bridge. Photos taken by AARoads (08/28/06).
After the Tank Farm Road intersection, the second and final intersection is with A Street to the Port of Pasco. U.S. 12 west shifts onto a freeway alignment after A Street. Photo taken by AARoads (08/28/06).
The first interchange on the nascent U.S. 12 freeway serves Kahlotus (unsigned Exit 15B) and Lewis Street (unsigned Exit 15A). ALthough not mentioned, Interstate 182 will begin shortly. Photo taken by AARoads (08/28/06).
Westbound U.S. 12 meets Exit 15B, Kahlotus. The next exit is Exit 15A, Lewis Street. Photo taken by AARoads (08/28/06).
Shortly thereafter is the exit for Lewis Street. After this ramp, Interstate 182 begins its westerly journey toward Richland. Photo taken by AARoads (08/28/06).
As traffic for Lewis Street departs, the next exit is Exit 14, Junction U.S. 395 north to Spokane. Much of the route to the north is freeway or expressway, which makes the journey to Spokane much quicker. Shortly after this overpass, U.S. 12 transitions directly onto Interstate 182, as evidenced by the next reassurance shield (see next photobox). Photo taken by AARoads (08/28/06).
Perspective from Interstate 182 and U.S. 12 West
Interstate 182 begins after the Lewis Street offramp and prior to Exit 14, Junction U.S. 395 north to Spokane. Photo taken by AARoads (08/28/06).
The first interchange on nascent westbound Interstate 182 is Exit 14, Junction Washington 397 south to Finley (truck route) and Junction U.S. 395 north to Spokane. Photo taken by AARoads (08/28/06).
A collector-distributor lane is formed at the U.S. 395/Washington 397 interchange. The right lane exits onto the collector-distributor lane, which in turn provides a direct link to U.S. 395 north (Exit 14B) and Washington 397 south (Exit 14A). Photo taken by AARoads (08/28/06).
Now on the collector-distributor lane, the first ramp connects westbound Interstate 182/U.S. 12 with northbound U.S. 395 (Exit 14B). Photo taken by AARoads (08/28/06).
A second Interstate 182 reassurance shield (along with a Lewis and Clark trailblazer) is posted at the U.S. 395 and Washington 397 overpass. The next exit provides the connection to Washington 397 south to Finley and Kennewick. From here, Interstate 182 and U.S. 12-395 follow a shared alignment for about two miles before separating at Exit 12. Photo taken by AARoads (08/28/06).
