U.S. Route 730 (US 730) is an east–west

US 395 in the city of Umatilla. US 730 and US 395 form a short concurrency within the city before the highways part, and US 730 continues northeast into Washington. The highway travels through rural Walla Walla County and ends at an intersection with US 12 south of Wallula
.

US 730 was created with the original US Highway System on November 11, 1926, traveling on the existing Columbia River Highway, established in 1917, from US 30 in Umatilla to

Primary State Highway 3
(PSH 3) in 1937. The highway was concurrent with US 395 from 1937 until 1985, traveling from Cold Springs Junction to US 410. US 30 was moved to a new route bypassing Umatilla and Irrigon in 1946, allowing for US 730 to be extended southwest to Boardman, later to an interchange with I-84.

Route description

US 730 runs 41.78 miles (67.24 km) in

United States Numbered Highway, or U.S. Route, and is the shortest existing highway in the system.[7] The highway is defined by the Washington State Legislature as SR 730, part of the Revised Code of Washington as §47.17.821.[8]

Oregon

Looking east on US 730 as it travels along Lake Wallula in Oregon, approaching the state border with Washington

US 730 begins at a

Cold Springs Junction, providing connections north to the Warehouse Beach Recreation Area and Hat Rock State Park on the Columbia River and south to the city of Pendleton. US 730 heads into Washington, traveling between a Union Pacific rail line and the canyon walls of the Columbia River Gorge.[11][12] An ODOT survey measuring traffic volume conducted in 2011 on US 730 calculated that the busiest section of the highway in Oregon was at its interchange with I-82, serving 11,800 vehicles, on average, while the least busy section of the highway was at the Washington state line, serving 2,500nbsp;vehicles.[13]

Washington

US 730 continues north from Oregon along Lake Wallula and around Clover Hill, reaching Wallula Junction in Walla Walla County. The highway intersects its spur route and turns east towards its eastern terminus at US 12 south of the community of Wallula.[14] In 2012, WSDOT calculated that the Washington section of US 730 served between 1,500 and 2,400nbsp;vehicles per day, on average.[15]

History

The highway that became US 730 within Oregon has been designated by the

San Diego, California, in 1937, becoming concurrent with US 730 between Cold Springs Junction and its eastern terminus at US 410 south of Wallula.[21][22]

US 30 was moved to a new section of the

Pendleton-Cold Springs Highway No. 236, became Oregon Route 37.[16][34]

The highway's eastern terminus in Wallula is planned to be moved further north to a new interchange with US 12 after the completion of the Burbank–Walla Walla divided highway in the 2020s.[35]
