MTIP: I-5: Willamette River Bridge - Bundle 220 Construction Year: 2012
Jurisdiction: Oregon Dept. of Transportation (ODOT) Mode: Road

Replace interstate bridge #08329 at Willamette River.

The purpose of the project is to improve safety and maintain connectivity and mobility for all users of I-5 over the Willamette River and the Eugene/Springfield metropolitan area.

It was not cost-effective to repair or widen the original I-5 Willamette River Bridge to accommodate projected traffic increases. An inspection of the original bridge in 2002 found it to have major structural problems that threatened its stability and safety. The original bridge also was designed using standards that are no longer appropriate for the size of longer, heavier modern freight trucks. The bridge has substandard shoulders, creating a safety problem.

ODOT opened a temporary bridge in 2004 as an interim solution to keep the route open for freight and other vehicles until a new bridge could be built. The temporary bridge was constructed using materials and methods that could be installed quickly, but that do not meet environmental, design or seismic standards for permanent freeway bridges.

Business Access During Construction? Yes

Spring 2009 - Winter 2014

Traffic Impacts:

Throughout the project, two lanes will be maintained in each direction on I-5 using staged construction with lane shifts. There will be occasional closures of the off- and on-ramps at Franklin Boulevard. There will also be occasional closures of Franklin Boulevard.

Pedestrians and cyclists, detour paths on the south bank of the Willamette River and in the Whilamut Natural Area ensure safe mobility around the construction areas for bicyclists and pedestrians. Kiosks located throughout the park provide updated path detour and construction information. Bicyclists and pedestrians may experience delays on paths on both sides of the river. Flaggers will direct path users, and detours will ensure continued connections between Eugene and Springfield. Bicyclists are subject to the same rules as motorists, including doubling of fines in construction zones for disobeying a flagger or riding on a closed road or path. Closures and delays are necessary to protect the safety of people using the paths, as well as construction workers.

Work Schedule:

The project schedule depends on weather and a number of other factors. Please check with this website or the other resources mentioned, for the latest information on schedule and traffic control.
