College Way Widening Under Interstate 5

Project Description: 

This project includes improvements to College Way beneath I-5 to add more lane capacity and relieve traffic congestion. Improvements include traffic signal modifications, adding two additional traffic lanes on both the north and south side of College Way, storm drain improvements, relocating of utilities, modifications to the I-5 bridge abutments to accommodate the road widening, installation of curb gutter, and sidewalk. This segment of College Way has heavy turning traffic at the I-5 interchange that causes blocking of through vehicles in the east/west direction. 


This project is funded by Federal Highway Administration (FHWA), 
the Washington Transportation Improvement Board (TIB), and a County economic development grant.
