The I-5/SR 501 interchange before the old bridge was demolished in October 2010

Overview
This project was constructed in two stages. Stage 1 began construction in 2009 and was complete in 2011. replaced the existing I-5 interchange at SR 501 in Ridgefield with a new bridge and improved on- and off-ramps. The project also widened SR 501 to two lanes in each direction, and added new turn lanes and sidewalks for pedestrian and bicycle travel along SR 501.

Construction on Stage 2 began in April 2012, and was complete in October 2012. Stage 2 built roundabouts and made other improvements to the SR 501/56th Place and Pioneer Street/65th Avenue intersections. Crews built additional sidewalks to connect to those built under Stage 1.

The new interchange improves traffic flow at the I-5/SR 501 connection and will accommodate future traffic growth while maintaining local access for drivers, pedestrians and bicycles. Drivers on SR 501 now have two lanes in each direction and turn lanes. Roundabouts keep traffic moving at the intersections of SR 501/56th Place and Pioneer Street/ 65th Avenue, and new sidewalks improve bicycle and pedestrian access across the interstate.

This project received stimulus funding from the 2009 American Recovery and Reinvestment Act (ARRA). This funding allowed WSDOT to move Stage 1 to construction. Stage 2 was funded by local agencies.
