Aberdeen announces start of US 101 Safety Improvements Project
Published 1:30 am Friday, April 3, 2026
The city of Aberdeen will begin construction in April on significant improvements to the U.S. Highway 101 corridor from the Chehalis River Bridge to the city limits of Cosmopolis. The project was awarded in February to Reed Trucking & Excavating, Inc.
The corridor improvements are designed to enhance safety, accessibility, and mobility for drivers, pedestrians, bicyclists, and transit users. Key project elements include:
Construction of new missing sidewalk segments
Installation of ADA-compliant pedestrian curb ramps
Intersection bulb-outs to improve pedestrian visibility
High-visibility pedestrian crossings
Buffered bike lanes with on-street parking
Dedicated transit pull-out stops
A “road diet” converting the existing configuration from two lanes in each direction to one lane in each direction with a center two-way left-turn lane
A recent local example of a similar “road diet” is the downtown Market Street project completed in 2025.
Funding for the project is provided primarily through $2.1 million of federal and state grants administered by the Washington State Department of Transportation and the Washington State Transportation Improvement Board. The balance of construction costs will be funded by the city of Aberdeen’s Transportation Benefit District.
During construction, motorists should expect shoulder closures, lane closures, lane shifts along U.S. Highway 101, and temporary side street closures. Work will continue through the summer and is tentatively scheduled for completion in late fall.
For safety, drivers and pedestrians are urged to remain alert, watch for changing traffic patterns, and obey all construction signage and flagging personnel.
