CDOT begins resurfacing Wadsworth from I-70 to 65th Avenue

May 3, 2021 - Jefferson County

The Colorado Department of Transportation and contractor Brannan Sand & Gravel recently kicked off a resurfacing project along Wadsworth Boulevard in Arvada from the Interstate 70 interchange to 65th Avenue. Work includes day and nighttime operations to repave the road and the I-70 on and off-ramps at Wadsworth, which will improve safety and the driving experience along this 2.5-mile stretch.

Other improvements include:

  • Bringing curb ramps to Americans with Disabilities (ADA) compliance
  • Installing a median at Wadsworth Blvd & 62nd Ave
  • Upgrading vehicle detection systems at all traffic signals within the project limits
  • Replacing the expansion joint for the bridge over Ralston Creek
  • New pavement markings

Travel Impacts

  • Single lane closures will be in effect during daytime hours Mondays through Fridays from 9 a.m. – 3 p.m.
  • Double-lane closure will be in effect during nighttime working hours from 6 p.m. – 6 a.m. Sundays through Thursdays. One lane of traffic will remain open during nighttime work.
  • No weekend work is anticipated. 
  • On and off-ramps will occasionally be closed for resurfacing during overnight hours. Please follow the detour signs to navigate around the area when closures are in effect.
  • Curb ramps will be temporarily inaccessible while under construction. These impacts will last a few days per intersection. Pedestrian detours will be in place.
  • Motorists should expect grooved pavement in sections of the project from July through September until paving operations are completed. Alternate routes are recommended if possible.
  • The anticipated completion date is December 2021; however, these operations are weather and temperature dependent, and this schedule could change.
  • Please drive safely through the work zone when crews are present.
