Ross Island Bridge Rehabilitation Project


Ross Island Bridge Rehabilitation Project
 
Current Status, July 2016 (7/1/16):
  • The bridge painting phase started in 2016 and will continue through fall 2017.*
  • Crews completed painting the final top coat on two spans (40 foot sections) and are currently painting the next sections on the west end of the Ross Island Bridge.
  • Sandblasting and painting is in process.
  • Current work is taking place on the west end of the bridge, and will continue from west to east during upcoming work seasons.
  • Current Traffic Impacts: None (all work is occurring under the bridge). For more information related to weekly traffic impacts, please also visit the Weekly Construction Updates web page.

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

 
 

Overview
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 will set up tarps to contain debris associated with sandblasting and painting in July/August 2015. Sandblasting and repainting the first section of the bridge is scheduled to begin in September. 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. Crews will move work platforms and the containment system between periods of active painting.
  • Additional maintenance near the Ross Island Bridge - on the OR43 (SW Macadam Ave) Ramp connecting to SW Kelly Ave. and SW Hood Avenues (Ramp scheduled to close Aug. 14-31, 2016)*
    • Roadway work is planned near the west end of the bridge at the Oregon Highway 43 (SW Macadam Ave) northbound ramp (under the Ross Island Bridge) connecting to SW Kelly Ave. and SW Hood Ave.
    • Construction on the OR43 (SW Macadam Ave) ramp will be closed from Aug. 14-31, 2016 (all hours, seven days a week).
    • Additonal nighttime closures may occur before or after the full closure (from Aug. 9-13 and Sept. 1-3).
    • **More information can be found by visiting the project website here.**
* Please note: 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 on the Ross Island Bridge. The project will cost $30 - $40 million, paid from state and federal funds.

WHAT TO EXPECT DURING PAINTING PHASE OF THE ROSS ISLAND BRIDGE

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.
