State Route 432 (SR 432) is a 10.32-mile-long (16.61 km) state highway in the U.S. state of Washington, serving the cities of Longview and Kelso in Cowlitz County. The highway travels east along the Columbia River from an intersection with SR 4 in West Longview through the Port of Longview and the termini of SR 433 and SR 411 in Longview. SR 432 crosses the Cowlitz River on a divided highway and ends at an interchange with Interstate 5 (I-5) in Kelso. SR 432 was established during the 1964 highway renumbering as SR 832, replacing a branch of Primary State Highway 12 (PSH 12) that had been routed through Longview and Kelso since 1937. SR 432 was established in 1968 and originally routed on Nichols Boulevard within Longview and was re-aligned onto its current route in 1991 after the opening of Industrial Way.
