Traffic signal, sidewalk improvements coming to US 101 in south Aberdeen

Changes also occurring at SR 105 Spur intersection in Westport

ABERDEEN – A project to upgrade traffic signals and make pedestrian improvements on US 101 in south Aberdeen will kick off at the end of May. Crews will also make sidewalk and intersection improvements on State Route 105 Spur in Westport.

Crews are scheduled to start work on Tuesday, May 30, to begin removing an aging traffic signal at the intersection of the SR 105 Spur/West Ocean Avenue and South Montesano Street in Westport. Stop signs will replace this signal, which has been flashing red for several years. This follows a thorough Washington State Department of Transportation review of traffic counts and needs at this location. The decision to make the switch to stop signs cuts the significant cost of a new traffic signal installation as well as ongoing maintenance costs.

Once the Westport location is complete, crews will begin rebuilding the traffic signals at the intersection of US 101 and SR 105 in south Aberdeen. The existing traffic signals near the base of the Chehalis River Bridge have reached the end of their service life and need to be replaced. WSDOT initially considered a roundabout at the intersection, but an in-depth review determined a roundabout was not a good fit here.

The sidewalks at both locations also will get facelifts and upgrades to improve these intersection crossings for all users under the Americans with Disabilities Act.

What to expect

Travelers on US 101 in south Aberdeen will see a combination of one lane in each direction or one-lane alternating traffic controlled by a flagger. The single-lane closures may bring up to 15-minute delays. Travelers can expect daytime or nighttime work.

In Westport on SR 105, crews will alternate one-direction of traffic at a time during working hours. Most work will take place during the day.

Temporary sidewalk closures with pedestrian detours will also occur at both locations.

WSDOT will announce lane closures in advance on the WSDOT app and real-time map. The contractor, Quigg Bros., Inc., expects to complete this project by fall 2023.

WSDOT urges drivers to slow down when passing through work zones to keep crews and all roadway users safe.
