OIPCB Working to Repair the Coos Bay Swing Span Bridge

Update September 20, 2018

The work barge that will be utilized during construction is estimated to arrive on site in the coming weeks.

The Port’s contractor is also working to finalize shop plans for replacement bridge component fabrication and will continue to survey the structure to finalize work plans for construction.

Contractors and engineers are working with the Port to finalize the Jacking and Shoring plans by the end of the month. Concurrently, the pilings support Jacking and Shoring work are in the process of being purchased.

Construction completion is still on schedule to return the bridge to rail service in the Fall of 2018.

Update August 9, 2018

The Oregon International Port of Coos Bay (Port) continues to work to restore the Coos Bay Swing Span bridge to rail service.  The bridge was closed to rail traffic following a structural failure in April of this year. 

The Port has selected a construction firm and steel parts fabricator to complete the necessary repairs to the structure.  Preliminary construction plans are completed, and the Port is currently working with contracted engineering consultants to develop design plans for a temporary shoring and jacking system.  Shoring and jacking will serve to preserve the surrounding components of the bridge during repairs.  The bridge is anticipated to reopen to rail service in the Fall of 2018.

The bridge serves as a critical component to the overall infrastructure of the Coos Bay Rail Line, which links Oregon products to the National Railway Network and the deep draft harbor at the Port of Coos Bay.  Access to the freight rail service is critical for the shippers utilizing it to move their goods to market. The shippers south of the Coos Bay Swing Span bridge employ nearly 600 people in Coos County.  In 2017, over 3000 rail cars moved to and from these businesses, representing approximately 40% of all rail traffic transported along the line.   The Port has and will continue to work closely with these shippers to develop interim solutions to transport goods until the bridge repairs are completed. 

Update May 23, 2018 

The work vessel and barge has repositioned to the South side of the Coos Bay Railroad Bridge this afternoon.  They are continuing the test and inspect the trusses, eye -bars and pins on the south side of the swing bridge.

Stantec has completed the scope of work and inspections on the Coos Bay Railroad Bridge.  The next phase will be determining the scope of repairs once Stantec provides the Port of Coos Bay with their inspection report.

Update May 21, 2018 

21 May 2018,  work has commenced to conduct visual and non-destructive inspection of the structural members on the Coos Bay Railroad Bridge at Coos River mile 9.0.  The work vessel and barge will be set up on the north side of the swing bridge today and will be removing the Osprey Nest on top of the Swing Span bridge under the USFWS depredation permit to a safe location and clean planned bridge inspection locations with hand tools.

Note:The Oregon International Port of Coos Bay intends to conduct visual and non‐destructive inspection of structural members on the Coos Bay Railroad Bridge at Coos Bay River Mile 9.0 May 21 through May 25, 2018. Work will be conducted from a work barge located along one side of the bridge center fender pier and will horizontally restrict the navigation channel on that side of the bridge by approximately 50 feet.  Vertical clearance on each side of the bridge will not be obstructed by the planned work. Planned workhours will be from 0800 to 2000 each day.

Update May 3, 2018

Coos Bay, Or. - The Oregon International Port of Coos Bay wants to share with our stakeholders and the public our intentions to repair the swing span bridge that has been out of service since Friday, April 13th. The Port and our engineering consultants have completed an analysis of the failure and are finalizing a construction plan to get the bridge back in working order. At this point, we are expecting a three-month time frame to conclude the repairs needed to get the bridge back to operational status.

While the ultimate cost of repairs is not yet known, The Port will cover expenses by leveraging funding already in place to execute the required repairs.

There has been a great deal of hard work done by the Port, Jordan Cove and local rail shippers to quickly stand up an interim solution connecting local shippers to the national rail network and ensuring ongoing production of Coos Bay products. Thanks in large part to Jordan Cove who have provided a site to facilitate an intermodal transfer area to be used as an interim solution until the bridge is operable.
