I-5 from Spokane Street to the I-90 interchange is an elevated bridge that is more than 40 years old. Aged and worn expansion joints and pavement posed a risk to drivers and required constant maintenance, with costly repairs and disruptive and repeated emergency lane closures. To help protect drivers and extend the life of the freeway, we replaced the expansion joints on the northbound bridge and resurfaced the northbound lanes. We also repaired the expansion joints on the southbound bridge.
Minimizes the risk of expansion joint failure, which posed a risk to drivers. The 1.13 miles of new pavement on northbound I-5 eliminates cracks and potholes and provides better traction.

Eliminates the need for costly and constant repairs and maintenance.
Partnerships & Cooperation
We selected contractor Concrete Barrier Inc. of Mukilteo to complete these bridge repairs.
We worked with numerous cities, businesses, professional associations, community groups and transit agencies to help commuters and other freeway users find ways to get around during the state's biggest construction closure ever (2 to 3 lanes of northbound I-5 closed around the clock Aug. 10-25, 2007).

This project was determined to be exempt from Section 106 Consultation per the Programmatic Agreement between the Washington State Department of Transportation, the Federal Highway Administration, the Advisory Council on Historic Preservation, and the State Historic Preservation Officer signed July 18, 2000.
