This project will construct a new I-5 interchange at SR 502 (NE 219th Street) in north Clark County. The interchange is intended to ease congestion and improve safety both northbound and southbound on I-5, improve safety at the NE 179th Street interchange by reducing congestion, improve safety on I-5 by reducing weaving between the junction of I-5 and I-205 and the existing exit, and help improve access to Battle Ground.
