DENVER (CBS4) – A major closure begins this weekend along Interstate 70 as part of the Central 70 project. The “Mile High Shift” will close the lanes of I-70 in a west and east direction between Washington Street and I-270. This closes on Friday, May 21st at 10 p.m. to Monday, May 24th at 5 a.m.

This closure allows crews to begin work on Mile High Shift. This will move all six lanes of I-70 traffic between Brighton Boulevard and Colorado Boulevard from the existing viaduct to the future lanes of I-70 heading west in the new sunken section of the interstate.

In addition, the crews will safely demolish the 57-year-old viaduct in order to build the future lanes of I-70 in an easterly direction.

Signs will be put up to help drivers control the entire weekend closure. Detours are as recommended:

• I-70 traffic going west: Travel west on I-270 to I-76, continue south on I-25, and continue on I-70 west from.
• I-70 Eastbound Traffic: Travel north on I-25, take I-76 east, travel east on I-270, and travel east on I-70 from.
