I-105: Willamette River Connectors and 1st to 7th Ave Viaducts Bridge Repair

Completed: No
Jurisdiction: Oregon Dept. of Transportation (ODOT) Mode: Road
Description:

Four I-105 bridges and associated ramps between the Delta Highway Interchange and downtown Eugene were built in the late 1960s and early 1970s and are in need of repairs and upgrades. Each structure needs guardrails that meet current crash standards, structural deck paving overlays, seismic retrofits, joint replacements, and concrete girder cracks repaired.

Another bridge was built to go over a future highway that was never built. Now this bridge is in need of repair. To avoid future bridge maintenance costs, the bridge is being removed and replaced with an embankment.

Project Map

Business Access During Construction? Yes
Road Closure:

Parts of this project will create noise. Noise restrictions will be enforced during night work, or a variance will be obtained if it is unavoidable.

The multi-use paths underneath the Willamette River Bridge on both banks will remain open during construction. Protection measures will be in place to ensure the safety of people on the path from work being done on the bridge above the path. 

Exact timelines are not known yet, but during part of the project there will be closures of the southbound Delta Highway ramp to I-105 westbound and the I-105 ramps at 6th and 7th. Notice of closures will be given well in advance.  

One two week closure of the Washington/Jefferson Street Park, including the restrooms, is planned. Otherwise, the park and restrooms will remain open during construction.

Timeline:

Construction is scheduled to begin in summer 2018 and will be completed in fall 2020.

Traffic Impacts:

Lane closures and detours will be necessary. To minimize disruptions during commute times, lane closures will be limited as much as possible and night work will be allowed.  

Funding:

Project Budget: $18 million
