Route description
US 12 begins in downtown
In Elma, US 12 exits at a
US 12 continues south concurrent with I-5 through Chehalis and Centralia before exiting again at exit 68 south of Napavine.[7] The highway then heads east along the Cowlitz River and passes through the town of Mossyrock, where it intersects SR 122. East of Mossyrock, US 12 runs just north of Mossyrock Dam and Riffe Lake. In the town of Morton, it intersects SR 7, which heads north to Tacoma.[8] It then ascends the Cascade Range, passing south of Mount Rainier, and intersects SR 123, which serves the Stevens Canyon entrance of Mount Rainier National Park.[9] 12 miles (19 km) east of this intersection, US 12 crosses the Cascades over White Pass at an elevation of 4,500 feet (1,372 m).[1][10] White Pass is the only crossing of the Cascades open year-round between I-90 over Snoqualmie Pass and SR 14 through the Columbia River Gorge.[10][11]
After it descends the mountains, US 12 intersects SR 410 (formerly US 410) west of Naches, which serves Chinook Pass, Cayuse Pass, and the White River entrance of Mount Rainier National Park.[9] East of Naches, US 12 widens once again to four lanes as it approaches the city of Yakima.[1] There, it has an interchange with I-82 and US 97 at exit 31.[12] US 12 then runs concurrently with I-82, bypassing the towns of Toppenish and Prosser and paralleling the Yakima River, until exit 102 near the Tri-Cities. At exit 102, it meets the western terminus of Interstate 182. US 12 and I-182 then run concurrently east over Goose Gap and through the Tri-Cities. In Pasco, I-182 ends, and US 12 intersects US 395.[13]
US 12 then heads south to the town of
History
The Washington section of US 12 was originally developed as a state highway in the early 20th century. It was incorporated into several later highways, including US 410.
Early years
The
Under a 1909 law, the State Highway Board surveyed a connected network of proposed state roads. Included was a westerly extension of SR 5 via
A 1923 restructuring of the system reassigned numbers to almost all the primary state highways.
U.S. Route 410
When the U.S. Highways were first established in 1926, US 12 ended in
Renumbering and realignments
The extension of US 12 to Aberdeen was approved on June 20, 1967, with US 12 taking over much of US 410's former routing.[37][40] However, where US 410 had crossed the Cascades at Chinook Pass, US 12 used the all-weather White Pass, replacing SR 8 and SR 14.[41] Signs were changed in late December 1967,[42] and the bypassed segments of US 410 became a new SR 8 between Elma and Olympia, and SR 410 between Tacoma and Naches.[43][44] Due to construction of the Mossyrock Dam on the Cowlitz River, which would create Riffe Lake and inundate parts of the valley, US 12 was relocated in December 1967 on a 16-mile (26 km) route that traveled through Morton.[45] The detour was opened early after the Nesika Bridge over the Cowlitz River was destroyed in a fire started accidentally by construction crews a month earlier.[46] The final project near the dam, a 1,136-foot (346 m) arch bridge over the Cowlitz River, opened in May 1968 and was primarily financed by Tacoma City Light; at the time, it was the longest concrete arch bridge in North America.[47][48]
The Montesano–Elma section of US 12 was moved to a new, 9-mile (14 km) divided highway in February 1969 after construction was completed on the last section of the Ocean Freeway.[49] Construction of a 6.5-mile (10.5 km) freeway to bypass downtown Walla Walla began in 1971 and was completed three years later at a cost of $13 million—about $5 million over the original estimate due to inflation.[50] The freeway opened on October 17, 1973, despite local opposition that compared the elevated overpasses to the Berlin Wall.[51] In 1985, US 12 was moved onto I-182 in the Tri-Cities, while its former route through Kennewick was replaced with an extension of SR 240.[52] The change was not formally submitted to the AASHTO until 2006.[53] The White Pass Scenic Byway was designated as a National Scenic Byway in October 2009.[54]
Local officials in Walla Walla County began lobbying for the replacement of two-lane sections on US 12 between the Tri-Cities and Walla Walla with a four-lane divided highway in the 1970s. The project was funded by the state government in 2001 and broken up into eight phases, of which six were completed between 2004 and 2012 at a cost of $180 million.[55][56] The seventh phase, bypassing Touchet and constructing 11 miles (18 km) of four-lane highway with two interchanges, began construction in 2021 and opened to traffic on June 2, 2023.[57][58] The original opening date of May 26 was delayed by a week after issues with a paint truck needed for road striping.[59] Construction of the final phase, bypassing Wallula Junction, remains unfunded as of 2022[update] and would require an extension of US 730 to a new interchange with US 12.[60][61]
