Dear Community Members,
From May 26th through June 4th, the Washington State Department of Transportation (WSDOT) completed improvements to the roundabout and bridge at Exit 119. To facilitate this work at night, Exit 119 was temporarily closed and all traffic, including commercial and industrial vehicles, was rerouted.
During the closure, the City temporarily waived the local ordinance restricting vehicles over 14,000 pounds on Center Drive to accommodate the approved detour route. The City also worked closely with local businesses to communicate construction impacts and provide information about the designated detour.
During the construction period, some GPS navigation systems directed truck traffic away from Center Drive and onto residential streets. The City coordinated directly with local businesses and trucking operators to address this issue and encourage the use of approved routes.
Construction was completed on June 4th and Exit 119 has since reopened and is fully operational. However, last week the City observed a recurrence of trucks GPS systems routing them into residential roads. City staff have been in daily communication with our industrial partners to ensure drivers are using the appropriate routes between the highway and local business destinations. In addition, the DuPont Police Department has been actively monitoring the situation and assisting in redirecting truck traffic away from residential neighborhoods when possible. Additionally, wayfinding signs have been added off Exit 118 and on Wilmington Road.
We understand the concerns this issue has created for residents and appreciate your patience as we continue working with our business partners, transportation providers, and navigation services to resolve it. The City remains committed to protecting neighborhood safety while supporting the transportation needs of our local businesses.
Thank you for your understanding and cooperation.
Sincerely,
City of DuPont
