The 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.
Construction will take place over two construction seasons in 2012 and 2013. The vertical alignment of all four viaducts must be set in relationship to the new tunnel floor elevation. If the floor is not lowered now, while the viaducts are replaced, the opportunity will be lost for the life of the viaducts, which is approximately 75-100 years.
What was accomplished in 2012?
Capital Concrete Construction, the primary contractor on the project, completed much of what it set out to accomplish in the first season.
The Aumsville, Oregon firm:
- 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
- Stayed on budget
What's in store for 2013?
To be completed this year:
- Placement of the remaining foundation piles for the half viaducts
- Construction of the half viaducts using precast beams and decks
- Repairs and sealing of the tunnel liner
- Repairs to the tunnel lighting
- Construction of the Variable Message Signs and weather station
