Expect delays for Salt Creek Tunnel project on Hwy 58

OAKRIDGE, Ore. - Highway 58 will close in both directions at the Salt Creek Tunnel east of Oakridge starting Wednesday night as work to repair and improve the tunnel begins its second season of construction.
 
During the day, the highway will be reduced to a single lane for two-way traffic, the Oregon Department of Transportation.

Flaggers and a pilot car will control travel in alternating directions. Motorists should anticipate delays of 5-20 minutes.

Highway 58 will be closed to all traffic in both directions between milepost 56 and milepost 59, Monday through Thursday nights between 8 p.m. and 6 a.m.

There is no local detour available and motorists will need to use an alternate route, ODOT said.
 
There will be no nighttime complete closures from Friday at 6 a.m. until Monday at 8 p.m. during the construction season.

The single lane restriction will remain in place during all hours when the tunnel is open.
 
During nighttime highway closures, motorists, other than freight haulers, have several alternate routes for travel from Eastern and Central Oregon to the Interstate 5 corridor.
 

  • In Southern Oregon-OR 140
  • In Central Oregon-US 20/OR 126
  • In North Central Oregon-US 26

 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, ODOT said.

Highlights of the construction project, according to ODOT, include:
 
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.
