Work crews will be doing significant construction on Interstate 25 north of Denver on evenings this week from Monday, Sept. 18, through Thursday, Sept. 21.
Southbound delays will be worst on Monday and Tuesday nights, when a full closure is scheduled for I-25’s southbound lanes near 136th Avenue. Northbound lanes also will be significantly delayed due to a partial closure.
Northbound delays will be worst on Wednesday and Thursday nights due to a full closure of northbound lanes at the same spot. Meanwhile, only a single southbound lane will be open those nights.
CDOT advises that drivers expect delays of up to 25 minutes as they take detour routes. The work is scheduled from 10 p.m. to 5:30 a.m. each night. The crews are installing storm-sewer infrastructure as part of the $98 million express-lane project.
