Ross Island Bridge Rehabilitation Project

Ross Island Bridge Rehabilitation Project
Current Status, March 2017 (3/8/17):
  • Crews completed painting the final top coat on nine sections of the bridge on Span 1 and Span 2.
  • The contractor is currently in process of installing an upper work platform on the north side of the Ross Island Bridge. 
    • The platform will be used for worker access, equipment and ductwork while the contractor works on the bridge spans over the water. Installation of the platform is expected to take several weeks.
    • Note to river users: steer clear of passing underneath the bridge where workers are installing their work platform as a safety precaution.
  • When weather conditions improve and the river level recedes, the contractor will bring a barge into the river to begin lifting platforms into place in the main span of the bridge.​ 
    • ​Note to river users: steer clear of the barge and lifting operation in span 3 when this work begins.
  • The bridge painting phase started in 2016 and will continue through fall 2017.*
  • Sandblasting and painting is in process.
  • Current Traffic Impacts: None (all work is occurring under the bridge). For more information related to weekly traffic impacts, please also visit ODOT's Weekly Construction Updates.
  • UPCOMING TRAFFIC IMPACTS: Night time single lane closures in each direction of US26 (Ross Island Bridge) scheduled for approximately three weeks (more detailed information will be provided prior to the lane closures).

* Please note: Schedules are subject to change due to weather and site conditions. 




The Ross Island Bridge is showing its age. Contractor crews working for the Oregon Department of Transportation began work in October 2014 to remove paint and rust, make repairs to the structure and repaint the steel supports. The work will occur seasonally over three years.

Project Need
The bridge was last painted in the 1960s. Since then, bubbles and cracks have appeared in the paint and rust has formed. The work will preserve the bridge's structural integrity and lengthen the lifespan of this key link in the regional transportation system.
Project Description:

  • Structural work (Fall 2014): Crews repaired the bridge’s weathered steel structure by removing rust, replacing rivets and making other structural repairs and improvements. Damaged truss members were replaced and new truss members were added to strengthen the bridge during the first phase.
  • Painting (2015-2017)*: Crews will remove old paint from the bridge’s steel supports and then repaint them to the historic deep blue-green color over three work seasons (May-October). Crews set up tarps to contain debris associated with sandblasting and painting. Sandblasting and repainting the bridge is in progress. Additional rivet removal and replacement also will occur during painting.
Crews will sandblast and repaint in sections, starting on the west end of the bridge and working east. They will move work platforms and the containment system between periods of active painting.
  • * Schedules are subject to change due to weather and site conditions.

This bridge project focuses on rehabilitating the existing, historic structure. No changes will occur to traffic flow or travel lanes for drivers, bicyclists or pedestrians as a result of this painting project. The project will cost $30 - $40 million, paid from state and federal funds.



Minimal disruptions to traffic:  No weekday traffic impacts will occur from this project. Some night or weekend lane closures will be necessary to move equipment and debris.
Temporary nighttime delays on the bridge sidewalk (located on the north side): Sidewalk delays are expected while contractors access the work zone beneath the bridge deck. Flaggers will direct sidewalk users and may close the sidewalk for up to 20 minutes at a time at night, Monday through Saturday.

Work areas under the bridge: Because of the bridge’s design, most  work will take place under the roadway. A work platform and containment system to catch old paint and debris will be visible under the bridge deck from nearby roadways and viewpoints.
Noise from sandblasting, rivet removal and rivet replacement: Noise will occur during daytime hours only.
