Full overnight closures of eastbound I-70 near Washington St. for bridge repairs start Tuesday, May 21

May 16, 2019 - Denver Metro Area, Colorado - Closures are scheduled for three nights, May 21 to May 23, from 8 p.m. to 5 a.m.


DENVER- As part of a project to repair nine bridges across the Denver Metro area, the Colorado Department of Transportation will work on the eastbound I-70 bridge over Washington St (MP 274.50) this month.  The goal of this project is to repair aging infrastructure, which improves safety for motorists and reduces wear and tear on vehicles and vehicle maintenance costs.

Crews will install hydraulic jacks to lift and replace the bridge bearing components. This work will require the eastbound I-70 bridge to be closed three nights, Tuesday May 21 - Thursday May 23 from 8 p.m. to 5 a.m.  

Motorists will follow a detour through the area. All lanes will be open by 5 a.m. for the morning commute. To navigate this closure, motorists will follow the suggested detour routes:

  • Eastbound I-70 traffic will be detoured onto the off ramp to bypass the closure and access the highway from the on ramp after Washington St.

  • Northbound Washington St. traffic will follow Brighton Boulevard, continue on 44th St and E 47th Ave

  • Southbound Washington St.  traffic will follow E 47th Ave towards 44th St and Brighton Blvd

  • Semi-trucks headed southbound on Washington St. will be detoured onto westbound I-70, exit at Pecos St., back on eastbound I-70, and reach Washington St. (See detour maps at bottom of release)

The schedule could change depending on weather.
