State Route 502 (SR 502, officially known as the Battle Ground Highway) is a 6.12-mile-long (9.85 km) state highway in the U.S. state of Washington, serving the city of Battle Ground in Clark County. The highway travels due east from an interchange with Interstate 5 (I-5) north of Mount Vista through Dollars Corner and Battle Ground to an intersection with SR 503, serving as connector between Battle Ground and I-5. Prior to the 1964 highway renumbering, SR 502 was part of Secondary State Highway 1S (SSH 1S), which was established in 1937. The highway traveled south from its current western terminus until the construction of a new interchange with I-5 in 2008, part of a project to widen SR 502 and install a median barrier on the roadway.
