Snohomish County Public Works completed a bridge replacement project for May Creek Bridge 559. The bridge provides vehicular access to rural residential communities in the Skykomish River Valley, east of Gold Bar. The old structure, which was built in 1975, was deemed structurally deficient due to scour and eroding conditions.
The new bridge has a longer 100-foot, single span, pre-stressed precast concrete girder superstructure. It is 28-feet wide curb-to-curb with two 11-foot travel lanes and 3-foot shoulders.
