WSDOT replaced the US 101 Elwha River Bridge in Port Angeles. Replacing the bridge has ensured that US 101 continues to be a reliable transportation facility for decades to come.
The new bridge is 40 feet wide and has two 12-foot lanes with two-8 foot shoulders. (The old bridge was 28 feet wide). A wider bridge creates a more comfortable crossing for travelers and provides adequate shoulder room for bicyclists and pedestrians. Additionally, the new alignment with US 101/Olympic Hot Springs Road has a gentler curvature than it previously did.
Built in 1926, the 3-span, 388-foot concrete arch bridge has served the community for more nearly 100 years. Over the last several years, the Elwha River has dramatically changed its course and flow, leading to significant erosion around the bridge foundations. As a result, WSDOT estimates the riverbed around the bridge’s piers has lowered 14 feet.
The lowered riverbed revealed the piers’ seals, prompting WSDOT to do borings to verify the depth of the foundations. The borings, done in October 2016, revealed the foundations are on gravel, not bedrock. This finding was in contrast to what the original 1926 engineering plans showed. As a result, WSDOT immediately installed almost 5,000 tons of riprap (large boulders) around both piers to help prevent further erosion. Additional bridge monitoring using tilt meters, crack meters, water flow meters, surveys and visual observations are underway until the bridge can be replaced.
Historical timeline of events
1913 - Elwha Dam was built
1926 - The US 101 Elwha River Bridge was built
1927 - Glines Canyon Dam was built
1954 - US 101 Elwha River Bridge was widened from a 20-foot bridge to 28 feet
2012 - Elwha Dam was removed
2014 - Glines Canyon Dam was removed
WSDOT remains committed in continuing to work with local and regulatory partners in this project including Federal Highway Administration, Department of Interior, Olympic National Park, Department of Archaeology and Historic Preservation, Lower Elwha Klallam Tribe, Department of Ecology, Department of Fish and Wildlife, Corps of Engineers and area jurisdictions.
Additional project benefits include
Transit stops on both the west and east ends of the bridge, locations of which were coordinated with Clallam Transit;
Relocating the intersection further east to provide better sight lines and intersection geometrics;
Installing illumination at the intersection (no illumination is there presently);
Building turn pockets on US 101 to Olympic Hot Springs Road;
Building a short acceleration lane on northbound US 101 from Olympic Hot Springs Road;
Restore the parking access that was there before with a gravel parking lot.
Elwha River Bridge public outreach

The Federal Highway Administration and Olympic National Park issued a joint Finding of No Significant Impact (FONSI) and Errata for US 101 Elwha River Bridge Replacement on November 22, 2021.
WSDOT and the Federal Highway Administration published the Environmental Assessment (EA) for the US 101 Elwha River Bridge Replacement Project on July 19, 2021. The comment period ended on August 18, 2021.

A design visual of what the proposed crossing will look like, including the restored gravel lot on the east end near Olympic Hot Springs Road.
Elwha bridge piers were discovered to be built on gravel, not bedrock. Erosion has significantly damaged the piers after the river changed course and flow over the years.
The new US 101 alignment will provide a much gentle curve with Olympic Hot Springs Road, wider lanes across the bridge, added illumination and transit stops.
The Elwha River Bridge will close for 9 days in the summer of 2024. Travelers will have to detour around the closure on SR 112 and SR 113.
