Full weekend closure of I-70 from I-270 to Steele/Vasquez begins Friday night, Sept. 20

September 12, 2019 - Denver Metro Area, Colorado


DENVER — As part of the Colorado Department of Transportation’s Central 70 Project, both directions of Interstate 70 will close between Interstate 270 and Steele/Vasquez in Denver so crews can set girders for the replacement bridge at Colorado Boulevard over I-70 and begin the I-270 bridge demolition. This closure begins 10 p.m., Friday, Sept. 20 and continues through 5 a.m., Monday, Sept. 23.

Full weekend closures allow construction crews to complete work that could potentially take months of nightly lane closures in just one weekend. Crews will also be taking advantage of this full highway closure to do additional work outside of the two major activities taking place. Motorists driving on I-70 through Denver to the eastern or western part of Colorado should plan their trip ahead of time.

In light of the start of football season, the Central 70 team worked to schedule this full weekend closure around Broncos home games as to avoid creating unnecessary impacts due to the closure.
