State Route 538 (SR 538, alternatively named College Way) is a 3.62-mile (5.83 km) long state highway located within the northern area of Mount Vernon city limits and the urban growth boundary, located in Skagit County, a subdivision of the U.S. state of Washington. The highway, which has existed as a county road since 1911, travels from Interstate 5 (I-5) in the west, passing former U.S. Route 99 (US 99), now Riverside Drive, and Skagit Valley College's main Mount Vernon campus before terminating at a roundabout with SR 9.
Before being designated Secondary State Highway 1G (SSH 1G) in 1937, the current roadway that is now SR 538 was a county road through farmland for 26 years. SSH 1G traveled between Primary State Highway 1 (PSH 1), also known as US 99, and SSH 1A until 1964, when the current designation of SR 538 was created. US 99 was bypassed by I-5 after 1966 and became Riverside Drive. The roundabout at SR 9 was constructed in 2007 while the Riverside Drive intersection was widened in 2009.
