Route description

SR 433 enters Washington and Cowlitz county on the National Register of Historic Places listed Lewis and Clark Bridge over the Columbia River. The highway travels northeast along the bridge for 0.54 mi (0.87 km) before dropping into the city and Port of Longview, intersecting the access road to the Port, Port Way. The highway continues north, paralleling railroad tracks belonging to the Columbia and Cowlitz Railway,[2] intersecting Port Way again, and gaining one lane in each direction for a total of four lanes before the highway terminates at an intersection with SR 432 and Industrial Way.[3] The highway has a posted speed limit of 35 miles per hour (56 km/h) for its entire length.[1] Oregon Way continues after the end of SR 433 into downtown Longview and SR 4.[3]

Every year the Washington State Department of Transportation (WSDOT) conducts a series of surveys on its highways in the state to measure traffic volume. This is expressed in terms of average annual daily traffic (AADT), which is a measure of traffic volume for any average day of the year. In 2009, WSDOT calculated 20,000 vehicles use the highway, with 12 percent of that traffic being trucks.[4] The entire highway is listed on both the WSDOT List of Highways of Statewide Significance,[5] which marks this portion of the highway as critical to connecting major communities in the state, and the National Highway System, a system of roads that are important to the nation's economy, defense and mobility.[6]

SR 433 and the Lewis and Clark Bridge form part of the Seattle to Portland Bicycle Classic, serving as the link between Washington and Oregon on the 202 mi (325 km) long bicycle race held annually.[7]

History

Before the 1964 state highway renumbering the highway was part of Primary State Highway 12.[8] Sometime between the renumbering and 1972 the highway was renumbered from SR 833, a branch of U.S. Route 830 (US 830), to the current SR 433,[9] a branch of SR 4, which replaced US 830 through the area. SR 433 originally terminated at Tennant Way,[10] but was truncated to Industrial Way in 1991 as part of the relocation of SR 432.[11]

The Lewis and Clark Bridge shot looking northeast. SR 433 begins in the middle of the bridge and travels towards the left.
