This project will repair or replace much of the concrete road surface along a seven-mile section of Interstate 5 between the south Cottage Grove interchange (Exit 170) and the Oregon 38 junction (Exit 162).
- Location: I-5 milepost 162.2-169.2
- Construction budget: $20 million (estimate)
- Bid let date: April 10, 2014
- Construction schedule: Spring 2014 to spring 2015
What is ODOT planning to do?
The seven-mile section of Interstate 5 between Martin Creek (milepost 169) and the Anlauf interchange (Exit 162) links Eugene and Cottage Grove to the Oregon 38 (Umpqua Highway) junction. The road surface in this area dates back several decades. Although it has held up remarkably well, the concrete is cracking and vulnerable to ongoing drainage problems.
At the north end of the project area, workers will dig out the existing highway to a depth of 3-4 feet, install a new rock base, and pour new 8-11” concrete travel lanes in both northbound and southbound directions. In the rest of the work zone, damaged concrete will be repaired or replaced and an additional 3” of asphalt will be paved over the road surface to protect the concrete below.
Additional work includes paving 10 interstate ramps in the project area, repairing the Oregon 38 overcrossing at the Anlauf interchange, and replacing substandard median barrier and guardrail.
Construction will begin in spring 2014 and continue until fall. Some additional work will be scheduled for spring 2015.
How will traffic be affected during construction?
I-5 traffic will be limited to one lane in each direction for most of the spring, summer and fall of 2014. Some ramp closures will be necessary.
From May to August, workers will rebuild the southbound lanes between Exit 170 (south Cottage Grove) and Exit 162 (Drain). During this time, the northbound lanes will be modified to carry one lane of traffic in each direction. Some southbound ramps will be closed.
During the fall, the process will be reversed. All traffic will be shifted into the southbound lanes, with one lane in each direction, so that workers can rebuild the northbound lanes. Some northbound ramps will be closed.
Work not completed by Thanksgiving will resume after the holiday season, when weather is favorable to construction.
ODOT will provide more information to the public and local media prior to and during construction.
