I-70 Bridge Over Washington Street

About the Project:

The Colorado Department of Transportation and ABCO Contracting will begin work to improve the I-70 bridge over Washington Street in Denver County. The project will include bridge deck repairs, storm sewer removal and replacement, bridge expansion device replacements, and median wall replacements. The project zone will span the length of the I-70 bridge (Mile Point 274.5 to MP 274.61) and will impact both east and westbound lanes.

Project Benefits

  • Critical repair work will provide greater safety for the traveling public.
  • Replacing bridge expansion devices will increase the overall longevity of the bridge's service life.
  • The project's bridge improvements will create smoother travel paths for motorists.

Work Schedule:

  • The project is anticipated to start the first week of May and be completed in late October 2023.
  • During the month of May, crews will be working daytime hours from 7 a.m. to 5 p.m., Monday through Friday.
  • After May, work will transition to nighttime hours from 10 p.m. to 5 a.m., Sunday night through Friday morning.

Traffic Impacts:

Motorists can expect the following impacts during the period of construction:

  • In May, the two Express Lanes in both directions on eastbound I-70 over Washington Street will be closed for crews to replace a storm sewer in the eastbound direction and repair the bridge approach slab in the westbound direction.
  • From June through the fall of 2023, there will be nighttime single lane closures on I-70.  This will include the Express Lane and general purpose lanes over Washington Street.
  • I-70 ramps to Washington Street will close intermittently during the night work with temporary detour routes in place.
  • Crews will be replacing expansion joints and large steel plates will be placed on the roadway to help facilitate work.
  • Drivers are encouraged to exercise extreme caution traveling over the steel plates. Please slow down within the work zone, watch for construction vehicles entering the highway, and leave plenty of space between vehicles.
  • Traffic impacts are expected to be minimal with delays up to ten minutes.
  • Refer to cotrip.org for real-time travel conditions and lane closures.
