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. 


Funding: 

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


Project Information: 

Bids were opened on September 27, 2018. On October 10, 2018, this project was awarded to Granite Construction. This project is expected to have a duration of twelve months. Night work will be performed if the contractor needs to close lanes beneath I-5. Lanes will be open during daytime commuting hours to lessen the impact to travelers.

Status:
The structural support of the slopes is complete under I-5 and more than half of the finished concrete wall is complete. Storm drainage near the walls and some of the signal foundations are complete. Work fusing the large stormwater pipes along Freeway Drive is complete. Installation of the pipe will be complete in September 2019.
