U.S. 101: Devils Lake Outlet, Schooner Creek and Siltcoos River Bridges Cathodic Protection Project

Construction Phase

Region 2: Willamette Valley and Northwest Oregon (Dunes City, Lincoln City, Lane, Lincoln)

​​​Three bridges on U.S. 101 Oregon Coast Highway will be repaired and cathodic protection installed.

Traffic Impact

Expect intermittent lane closures. Single lane closures will be allowed at night when traffic volumes are lower. Temporary traffic control will be in place to guide travelers through the work zone. Sidewalks on each side of the bridges will be closed periodically. Occassionally, it may look like there is nothing happening in a closed lane, but our crews are likely repairing cracks under the bridge. Traffic can't use the location above the repair sites while cracks are being repaired from underneath. 

Construction Impacts

Hydroblasting the bridges to remove the bridge rails for replacement and spraying zinc coating for the cathodic protection are noisy. Neighbors will be notified of construction schedules and what to expect.

D River:

The contractor will be cutting off the western bridge rail and closing the sidewalk for the next couple months. They will one night next week to complete the cutting and the remaining work will be done during the day. Work also continues underneath the bridges and steel plates are being used to protect the work crew. Short-term closures will be needed to move the steel plates as work progresses.​

Schooner Creek: 

A platform is being installed under the bridge and damaged concrete sections repaired. Crews are working at night for the next 1-2 weeks to strengthen the girders and install steel bars through the bridge deck. The eastern sidewalk is expected to be closed starting April 16 and lasting approximately 2 months while the contractor replaces the bridge rail. Expect minor delays.

Siltcoos River Bridge:

Concrete repair and reinforcement work is underway under the bridge. The east rail has been removed in advance of widening the deck and installing new railing. The bridge is one lane with traffic being controlled by a temporary traffic signal. 

Check for construction status and current travel conditions.


​Construction is scheduled for 2018 - 2021.

D River:

  • Construction began in September 2018, scheduled to last 16 months
  • Construction hours will vary based on the activity Winter -Spring - Fall

Schooner Creek:

  • Began July 15, 2019, and is scheduled to last 21 months
  • Night time closures 
  • Lanes will be closed from 8 p.m. to 6 a.m.
  • Traffic is flagged through the work zone during lane closures
  • Year-around construction of 10 hour shifts

Siltcoos River:

  • Will begin in April 2020, scheduled to last 18 months
  • Construction hours are TBD

A​ccess for pedestrians, including those with disabilities, will be available and identified through or around work zones.​



​These bridges have deteriorated from the salt air on the coast and are in need of repair. If nothing is done, the bridges would eventually have to be replaced. They might also need to be load rated, meaning that large vehicles over a certain weight would not be able to travel over them.

The bridges will receive titanium and steel reinforcements on the bridge deck and along the girders under the bridge to strengthen them. This will require cutting narrow slots and drilling small holes to insert the reinforcements, which will then be secured to the bridge with an epoxy.

Bridge rails will be replaced with new rails that meet current standards. A variety of methods will be needed to remove the old rail while not damaging portions of the bridge that remain, including chipping and hydro-demolition.

The bridges will also receive cathodic protection, which provides a shield of protective coating to prevent the steel from corroding.

​This is one of a series of bridge cathodic protection projects along the Oregon Coast, designed to keep the structures in service for years to come.
