Maple Heights Bridge Seismic Retrofit

Map this project on the interactive project overview story map.



Purpose


The existing three-span 300-foot bridge, built in 1979, is generally in good condition. The bridge is not in need of replacement but has some seismic vulnerabilities that need 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.

Project Description


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 will address current seismic vulnerabilities by improvements to the bridge girder abutment seats and by adding steel jacketing to the concrete support columns.
