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.

Project Update (11/1/2019):
Pavement restoration and striping on Freeway Drive is complete. Wall fascia panels under I-5 are also complete. Signal mast arms are installed and prepared activated. Curb gutter and sidewalk on the south side of College Way has been completed; pedestrian traffic will be shifted to the new sidewalk during the waterline construction on the north side which begins on November 4th and continues for 2-3 weeks.

The next major effort will be the installation of the new waterline on the north side of College Way which will begin November 4, 2019, and continue through the end of the month. This will involve periodic closures of the outside westbound lane on College Way.
