I-5: Martin Creek to Anlauf Paving

Project News

I-5 down to one lane south of Cottage Grove
Interstate 5 is reduced to one lane in each direction at milepost 168-170 until mid-November due to road construction on the Martin Creek-Anlauf Paving project. I-5 motorists should expect congestion and possible delays south of Cottage Grove during peak travel times.
Motorists should also look for intermittent single-lane closures elsewhere in the work zone, between Exit 162 (Drain/Oregon 38 junction) and the Lane/Douglas County line (milepost 168).
The Exit 170 (south Cottage Grove) northbound off-ramp is closed until mid-November. Motorists are advised to use alternate routes. All ramps at Exit 174 (Cottage Grove) remain open.
The southbound on-ramp at Exit 170 is scheduled to remain open during this construction phase. However, motorists planning to enter I-5 southbound should expect delays up to 20 minutes due to construction activity on the ramp.
From mid-September to early October, motorists should watch for intermittent weeknight (Sunday night to Friday morning, 7 p.m. to 9 a.m.) closures of the northbound ramps at Exit 162 and Exit 163 (Curtin) due to paving work. When the ramps at one exit are closed, all ramps at the other interchange will remain open. Additional information will be posted on roadside electronic message boards.

Project Information


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).

Project facts

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.

Traffic impacts
ODOT will provide more information to the public and local media prior to and during construction.
