I-70 B 1st Street & Grand Avenue - Construction Phase

Work this Week

Oct. 18, 2021

Concrete paving continues on CO 340/Broadway and the westbound lanes of I-70B in the project area.

  • The southwest entrance of the Grand Central Shopping plaza will close for scheduled work on CO 340. Access to the shopping center is the new US 6 frontage road, which can be reached from Mulberry St. or eastbound I-70B. Concrete for curb, gutters and sidewalks will be poured at this location.
    Traffic on Mulberry St., in front of Monumental Brewing, will be single-lane alternating traffic. Motorists should anticipate flaggers and follow their direction.
  • Traffic on I-70B from Main St. to the northern end of the project, up to American Way, continues in a head-to-head configuration in the eastbound lanes. This traffic configuration is in place 24-hours a day/seven days a week.
  • Both Rood and White Streets are open on the west side of I-70B but remain closed on the east side of I-70B.
  • The extended closure of North 1st St. will be in place until late October/early November between I-70B and Chipeta Ave. Access to businesses on North 1st St. will remain open. The preferred alternate route for access to North 1st St. is from North Ave., with a detour in place from Gunnison St. to 4th St. to Grand Ave.
