- Construction of a new I-5 Chamber Way overpass in Chehalis to begin in 2017.
The Washington State Department of Transportation will replace the existing I-5 Chamber Way overpass with a taller, wider structure.
On the morning of Friday, July 22, 2016, a semi-truck hauling a pair of excavators hit a portion of the Chamber Way bridge that spans over southbound I-5 in Chehalis, causing significant structural damage.
For the safety of the traveling public, the damaged span was demolished and a temporary bridge is currently in place.
Why is WSDOT
building a new Chamber Way overpass?
The existing overpass was built in 1958 and does not meet modern design standards. The Chamber Way overpass is a two lane bridge spanning across the interstate, and is only 14 feet 8 inches above I-5.
WSDOT demolished a portion of the bridge that was damaged by an oversized load and installed a temporary bridge in the summer of 2016.
The End Result
A wider, taller overpass will keep people in Chehalis connected between a vibrant commercial center west of I-5 and the city center.
The new overpass will be incorporated into a future project that will add improvements to I-5 and modify the adjacent intersections.
Safety - The new overpass will replace the existing structure and temporary bridge that is currently in place.
Mobility - Chamber Way will have two lanes in each direction across I-5, with improved bike and pedestrian access.
