Snohomish County Public Works is planning 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 existing structure, which was built in 1975, has been deemed structurally deficient due to scour and eroding conditions.
Construction for the replacement is projected to take place 2017. It includes a longer 100-foot, single span, pre-stressed precast concrete girder superstructure. The replacement bridge will be 28-feet wide curb-to-curb with two 11-foot travel lanes and 3-foot shoulders.
