A contractor for ODOT will close OR 58 (Willamette Hwy.) at the Salt Creek Tunnel (milepost 56) from 8 p.m. Monday, June 4 through 6 a.m. Friday, June 8.
During that time, no through traffic will be allowed at the location and motorists should find an alternate route across the Cascades.
The community of Oakridge will remain accessible from the west and the communities of Willamette Pass and Crescent Lake will remain accessible from the east.
Depending on the type of vehicle, alternate routes include OR 126, US 20, OR 22, OR 140, OR 138 and OR 140. Commercial truck operators should check with ODOT?s Motor Carrier Transportation Division over-dimension unit for restrictions, at (503) 373-0000.
During the closure, the contractor will excavate and rebuild the tunnel floor as part of the OR 58: Salt Creek Tunnel and Half Viaduct project.
Nightly closures scheduled the following week
The project will also result in nightly closures of the highway at the tunnel and single lane restrictions during the day. The closures and restrictions will be in place until construction ends in mid-October. Similar closures and restrictions will occur in 2013, during the second year of the project.
The highway schedule and impacts to motorists in 2012 are as follows:
? Complete day/night highway closure: 8 p.m. Monday, June 4 through 6 a.m. Friday, June 8, 2012
? Closed completely at night Monday - Thursday, from 8 p.m. - 6 a.m. beginning Monday, June 11
? Open to a single lane of travel Monday - Thursday, from 6 a.m. - 8 p.m.
? Open weekends to a single lane of travel from Friday 6 a.m. until Monday 8 p.m.
? Travel is restricted to a single lane with pilot cars. Expect 20 minute delays.
? No complete daytime closures in July or August.
? Oakridge will always be open for business from the west.
? Crescent Lake and Willamette Pass will always be open for business from the east.
Project will modernize a historic tunnel
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
The $9.4 million contract was awarded to Capital Concrete Construction, Inc., of Aumsville, Ore.
