Seabeck Holly Road Bridge #20 at Anderson Creek

This project replaces the Seabeck Holly Road Bridge #20 at Anderson Creek. A concrete girder bridge will replace the existing timber bridge. The contractor, Pacific Pile and Marine, started construction July 25, 2017 and anticipates completing the project in December 2017.

The existing Seabeck Holly Road Bridge is a 29-foot timber structure built in 1950. The aging timber bridge is showing signs of deterioration and no longer meets the sufficiency rating for current standards. The proposed longer bridge will also help to improve stream function and eliminate scour in high flow events.

Seabeck Holly Road is the only suitable emergency response route to the Holly community, therefore the road will remain open at all times during construction. Travel will be restricted to one lane of alternating traffic in the work zone. Flaggers will direct traffic through the work area minimizing delays to the maximum extent possible. Immediate access for emergency vehicles is maintained at all times.

The adjacent approach of Old Holly Hill Road NW—at the East end of the bridge—will close for the duration of the project so the contractor can stage equipment. Pedestrian access on both Seabeck Holly Road NW, and Old Holly Hill Road NW will be maintained at all times throughout the construction period.

The contractor started the project July 25, 2017 and is expected to be complete by the end of December 2017.
