Upcoming overnight full closures on I-76 between  Federal and Sheridan boulevards for bridge work

Travel Advisory

September 4, 2020 - Denver Metro Area

ADAMS COUNTY — Motorists can expect overnight full closures of Interstate 76 between Federal and Sheridan boulevards beginning Sept. 9 for bridge welding work on the I-76 over Clear Creek Bridge Rehabilitation Project. The project began in June and will improve aging infrastructure on the bridge along I-76 between Federal and Lowell boulevards from Mile Point 2.84 to MP 3.07. This work will extend the life of the bridge and provide the safest travel for motorists.

Motorists should be advised of the following major impacts to the interstate beginning after Labor Day:


Between Sept. 9 and Oct. 13, there will be 20 nights of full closures on I-76 between Federal and Sheridan boulevards. Crews will be welding on the bridge, during which no traffic is permitted on the bridge structure as a safety measure. Full closures will take place overnight; no daytime full closures will occur. 

  • Work Hours: Overnight Mondays through Thursdays, from 8:00 p.m. to 5:00 a.m. 


Below are the detour routes for general interstate traffic and local traffic. These detour routes will also be posted on message boards throughout the project zone. 

For general I-76 traffic

Motorists are encouraged to detour around the full closure via I-70 and/or I-25. Motorists can expect the detour to add an estimated 20 minutes to their route.

  • EB I-76 Traffic: Instead of exiting onto I-76, motorists are encouraged to stay on eastbound I-70, exit onto northbound I-25 and take that to the eastbound I-76 exit.

  • WB I-76 Traffic: Motorists are encouraged to detour from I-76 onto southbound I-25 to westbound I-70.

I-76 will be closed between Federal and Sheridan boulevards and motorists will use these streets as their primary detour route:

  • EB I-76 Local Traffic: I-76 will remain open to local traffic between I-70 and Sheridan Boulevard. Motorists traveling eastbound on I-70 can take the exit for I-76 and exit onto south or northbound Sheridan Boulevard. Otherwise, motorists can stay on eastbound I-70 and use northbound Federal Boulevard to get back to eastbound I-76.

  • WB I-76 Local Traffic: I-76 will remain open to local traffic between I-25 and Federal Boulevard. Motorists traveling westbound on I-76 can exit onto north or southbound Federal Boulevard. Southbound Federal Boulevard will connect traffic back to westbound I-70.

The following tips are to help you stay safe while traveling through maintenance and construction work zones.

  • Do not speed in work zones. Obey the posted speed limits.

  • Stay Alert! Expect the unexpected.

  • Watch for workers. Drive with caution.

  • Expect delays, especially during peak travel times.

  • Allow ample space between you and the car in front of you.

  • Anticipate lane shifts and merge when directed to do so.

  • Avoid using mobile devices such as phones while driving in work zones.

  • Turn on headlights so that workers and other drivers can see you.

  • Be especially alert at night while driving in work zones.

  • Be patient!


Safe transportation infrastructure is essential for all of us, particularly for emergency first responders and freight drivers as Colorado navigates the COVID-19 pandemic. With that in mind, CDOT maintenance and construction crews follow social distancing and other health safety measures to reduce COVID-19 exposure on the worksite. The Colorado Department of Public Health and Environment announced guidelines for construction activities. The public is urged to join the campaign for #DoingMyPartCO by practicing social distancing and wearing face masks. As traffic returns to normal levels, motorists must drive cautiously and heed the speed limit so all of us can return home safely.
