Project Overview

The historic Old Youngs Bay Bridge and Lewis & Clark River Bridge, each more than 85 years old, are located in a severe marine environment. Even with ongoing maintenance and repairs, deterioration occurs. ODOT plans a repair project for both bridges that will extend their useful live for more than 20 years. Bids will be opened in October 2013 with work to begin in early 2014. Project construction is expected to continue through 2017-2018. Estimated cost is $19 million.

These key elements of the bridges need repair:

  • The approaches to both bridges are supported with treated wood substructures, which has deteriorated with timber piles, sill caps and cross bracing all affected.
  • The Lewis & Clark River Bridge has deterioration of the wooden under-course which causes continued failure of the asphalt surface.
  • The steel central lift spans have corrosion and rust.
  • The electrical and mechanical systems on the Old Youngs Bay Bridge are original 1920’s equipment that are past their useful life and need to be upgraded to meet operational and safety needs for marine and highway use.

Throughout the project, motorists can expect delays due to intermittent bridge and lane closures. Both bridges will not be closed at the same time.

Public notice will be provided before any closure with dates and designated detour route.
