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.
During the first construction season in 2012, the contractor:
- Lowered the tunnel floor by 18-inches
- Poured and paved the new tunnel floor
- Constructed a new, improved drainage system in the tunnel
- Placed approximately half of the foundation piles for the half viaducts
This year, the project is scheduled to:
- Place the remaining foundation piles for the half viaducts
- Construct the half viaducts using precast beams and decks
- Repair and seal the tunnel liner
- Repair the tunnel lighting
- Construct Variable Message Signs, TripCheck camera, and weather station
Capital Concrete Construction, Inc. of Aumsville, Oregon was awarded the $9.4 million low–bid contract.
