Overview
WSDOT worked with the city of Federal Way to make improvements to the southbound I-5 off-ramp to South 320th Street in Federal Way. Crews widened the ramp from three to five lanes, upgraded lighting, modified signal timing and built a retaining wall.
 | Improves Safety
Widening the ramp is expected to improve safety by preventing traffic from backing up onto southbound I-5, which can lead to collisions. New lighting, signing, guardrail and a crosswalk also will improve safety in the area.

 | Relieves Congestion
The wider ramp is expected to ease backups from the high number of vehicles exiting from southbound I-5 to South 320th Street.
