Index Galena Rd, Howard Creek Bridge 496

Description


Howard Creek Bridge 496 is located at Mile Post 9.0 on Index-Galena Road where it crosses Howard Creek south of the North Fork Skykomish River in the Mount Baker – Snoqualmie National Forest.

The bridge is a single span, 61-foot long structure built in 1976. The log girders that were used to build it are deteriorating and the the bridge is currently “structurally deficient.” Traffic is restricted to one lane, and a 5-ton weight limit has been in effect since August 27, 2008.

The county has received federal funding from the Washington State Department of Transportation's Bridge Replacement Advisory Committee (BRAC).

The proposed design is for an 80-foot long single-span bridge. It will have steel girders and a concrete deck. It will be 28-feet wide for two lanes of traffic. 

Traffic impacts


During construction there will be no access to Index-Galena Road between milepost 6.4 and 9.0.

Schedule

Construction is planned to begin in spring 2017.
