OR 58: Salt Creek Tunnel and Half Viaducts

Important New Information

There will be no project construction in 2014, as the contractor and ODOT work toward a mutual termination of the contract.  The project will be completed at a later date. To learn more, click here. 

 

Construction Activity in 2014    
 
There will be intermittent activity at the project location as ODOT clears the site and makes minor adjustments to the roadway, as necessary.  There are no scheduled complete closures in 2014 and any lane restrictions will be short-lived.

 

Overview
 
 
/ODOT/HWY/REGION2/PublishingImages/a5/sct1_sm.jpgThe project is located at the Salt Creek Falls Tunnel, east of Oakridge on OR 58 (Willamette Highway) at milepost 56.
 
Built in 1939, the tunnel needs serious repair and the adjacent west half viaduct, and the three east viaducts are failing and need to be replaced.  The half viaducts have exposed reinforcement bar, severe cracks in concrete and are currently braced and supported by   temporary timber bracing that ODOT maintenance put in place in 2008.  In addition, the tunnel liner is cracked and leaking; the tunnel has limited vertical clearance; and the tunnel floor is in disrepair.
 
The OR 58: Salt Creek Tunnel and Half-Viaduct project will:
  • Replace the half viaduct west of the tunnel
  • Replace  the three half viaducts east of the tunnel
  • Repair the tunnel liner
  • Lower the tunnel floor
  • Construct variable message signs east and west of the tunnel.
    
 
Project History

 

Significant delays in construction this season in 2013 affected the $9.37 million project to rebuild four half-viaducts and repair and improve the tunnel liner.  ODOT and the contractor were in disagreement over the cause of the delays.   
 
The contractor informed ODOT that  a third construction season would be necessary to complete the project.
 
The construction schedule was to be extended to the 2014 construction season. To learn more, click here.
 
 The 2014 extension has now been cancelled as ODOT and the contractor work toward a mutual termination of the contract.  The project will be completed at a later date.
