Motorists should plan for detours and travel delays during bridge demolition work on I-70 over 32nd Avenue

Travel Advisory

April 3, 2022 - Central/Eastern Colorado - 32nd Avenue will be fully closed under the bridges for four nights

Jefferson County ― Starting on Monday, April 4, and lasting every night until Thursday, April 7, the Colorado Department of Transportation will begin removing the easterly portion of the westbound bridge on Interstate 70 over 32nd Avenue. During this work, 32nd Avenue under the bridges will be fully closed each night (April 4-7) from 8 p.m. to 5 a.m. during the removal process for safety reasons. Additionally, some lane closures will be in place overnight in both directions of I-70 from Exit 263 (Colorado Mills Parkway) to Exit 266 (Ward Road/CO 72) to accommodate access to the site. This work is part of CDOT’s I-70 over 32nd Avenue bridge replacement project.

Traffic Impacts April 4-7

32nd Avenue nightly full closure:

During this bridge demolition work, 32nd Avenue will be fully closed overnight from 8 p.m. to 5 a.m. Monday, April 4 to Thursday, April 7. Motorists can expect the following:

  • No access to westbound 32nd Avenue from Youngfield Street
  • No through access on 32nd Avenue from the west side of I-70 to Youngfield Street
  • No access to eastbound 32nd Avenue from westbound I-70 Exit 264 (Clear Creek Drive/32nd Ave)
  • Detour signage and devices will be present to direct traffic, cyclists, and pedestrians to 40th Avenue to bypass the closures (see detour map below)

Westbound I-70 overnight lane closures:

A double lane closure will be in place on westbound I-70 from 9 p.m. to 6 a.m. Monday, April 4 to Thursday, April 7. A single lane closure will be in place on eastbound I-70 from midnight to 6 a.m. Thursday, April 7

  • The lane closures are necessary for crews to safely access the area to remove the easterly portion of the westbound bridge and lower it to the ground below on 32nd Avenue.

During the overnight demolition work, area residents and businesses will be subject to some construction noise and bright lights. CDOT appreciates the public’s understanding during these short-term overnight disruptions as demolition work on I-70 is considered critical and cannot be performed during daytime hours without impacting the flow and safety of the traveling public.

Detour Routes

During the overnight closures of 32nd Avenue under I-70, all vehicular, cyclist and pedestrian traffic will be detoured to 40th Avenue (see map) to bypass the closures. This includes both westbound and eastbound I-70 traffic exiting at the Exit 264 off-ramps.

From westbound I-70

  • To access eastbound 32nd Avenue from westbound I-70, motorists will be able to exit at 264 (Clear Creek Drive) and will be detoured to 40th Avenue following the signs.
  • To access westbound 32nd Avenue from westbound I-70, no detour or impacts will be in place. Take Exit 264 Clear Creek Drive as usual.
  • This detour route is only expected to add up to five minutes of extra travel time.

From eastbound I-70:

  • To access eastbound 32nd Avenue from eastbound I-70, take Exit 264 (Youngfield) as usual and head east at 32nd Avenue.
  • To access westbound 32nd Avenue from eastbound I-70, motorists will be able to exit at 264 (Youngfield) and will be detoured to 40th Avenue following the signs.
  • This detour route is only expected to add up to five minutes of extra travel time.

Pedestrian/cyclist access:

  • There will be no pedestrian or cyclist access to and from 32nd Avenue between Clear Creek Drive to the west and Youngfield Street to the east during the overnight (8 p.m. to 5 a.m.) demolition work.
  • Pedestrians/cyclists should follow the pedestrian detour signs that will be present through the work zone.
  • The suggested route is north on Youngfield Street to 40th Avenue, then west to Clear Creek Pkwy, then south to 32nd Avenue.
  • This detour will add significant walking time to pedestrian travel. Please refer to the map for the detour route.
