CDOT announces overnight I-25 lane closures in Colorado Springs, June 5

Late-night drivers trying to slip through Colorado Springs before a mountain run faced a tighter window on Interstate 25, where CDOT and SEMA Construction set overnight double-lane closures near Garden of the Gods Road. The work hit the stretch between Exit 145 at Fillmore Street and Exit 146 at Garden of the Gods Road, a corridor that carries airport transfers, hotel check-ins and early departures into the Pikes Peak region.

Northbound I-25’s left lane closed at 7 p.m., then double-lane closures ran from 10 p.m. to 5 a.m. All lanes reopened by 6 a.m. Saturday. Southbound I-25 followed a similar pattern, with the left lane closing at 8 p.m., double-lane closures running from 10 p.m. to 4 a.m., and all lanes reopening by 6 a.m. Saturday. CDOT said the work was needed for bridge repairs at Garden of the Gods Road and warned that noise and vibrations were expected.

The overnight restriction mattered most for travelers moving through the city during the narrow hours when many weekend itineraries are at their most fragile. Late arrivals into Colorado Springs, predawn departures toward trailheads, and anyone connecting from the airport to lodging near the west side could have hit delays as through traffic was squeezed into fewer lanes. CDOT also reduced the speed limit to 55 mph on I-25 from mile point 144 to mile point 146, adding another layer of slowdown through the work zone.

The closure sat inside a much larger I-25 improvement project that began at the end of October 2023 and is expected to finish in late August 2026. The $62 million job covers auxiliary and continuous merge lanes, resurfacing, drainage fixes, permanent stop signs at Chestnut Street after completion, reconstruction of the Ellston Street bridge, and deck repairs on the Garden of the Gods overpass.

CDOT tied the project to community growth and business expansion, and study documents said the upgrades were meant to address crashes involving side-swipes, fixed objects and wildlife. During most of the construction period, three through lanes have been maintained in each direction except for occasional off-peak or nighttime closures, making these overnight restrictions part of a long-running traffic pattern rather than a one-off disruption.

For anyone trying to punch through Colorado Springs after dark or roll out before sunrise, the message was clear: the I-25 corridor between Fillmore Street and Garden of the Gods Road was not a place to assume an easy pass-through.
