The project is substantially complete. To improve drivability and reduce traffic noise, the City’s contractor will perform additional work beginning Tuesday, June 15. The new work will require a single-lane closure on Mukilteo Blvd. for approximately three weeks, weather depending. Temporary automated traffic signals will be in place on each side of the bridge to facilitate alternating one-way traffic control. Expect delays through the construction area.
The existing three-span 300-foot bridge, built in 1979, was in generally good condition. The bridge was not in need of replacement but had some seismic vulnerabilities that needed to be addressed. The bridge is one of three bridges along Mukilteo Boulevard that provide vital access to the Boulevard Bluffs neighborhood. The loss of any combination of two bridges along this section of Mukilteo Boulevard due to a major seismic event would result in potential isolation for parts of the neighborhood. The City is focusing on this bridge and the Edgewater Bridge as part of our earthquake hazard mitigation efforts.
The bridge is located along Mukilteo Boulevard near Harborview Park. The bridge spans Glenwood Creek and is a vital link for the Boulevard Bluffs neighborhood. The seismic retrofit work addressed seismic vulnerabilities by improvements to the bridge girder abutment seats. It also addressed drainage and expansion joint issues.
