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. The project was completed on June 8, 2018.

The prior Seabeck Holly Road Bridge was a 29-foot timber structure built in 1950. The aging timber bridge showed signs of deterioration and no longer met the sufficiency rating for current standards. The new longer bridge will 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 remained open at all times during construction. Travel was restricted to one lane of alternating traffic in the work zone. Flaggers directed traffic through the work area minimizing delays to the maximum extent possible. Immediate access for emergency vehicles was maintained at all times.

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