Overnight closures of I-25 beginning tomorrow

EL PASO/DOUGLAS COUNTIES – Northbound Interstate 25 is closing for three nights this week at the County Line Road Interchange (Exit 163), just north of Monument, for paving operations. 

WHEN: Wednesday, Aug. 25, Thursday, Aug. 26 & Friday, Aug. 27 – 8 p.m. to 5 a.m.

DETOUR: Northbound I-25 traffic will funnel into one lane south of the County Line Road bridge, and detour around the closure using the newly constructed northbound I-25 off- and on-ramps at County Line Road. Use the Colorado Highway 105 interchange (exit 161) for local access and access to northbound I-25. See detour map below.

The County Line Road Bridge over I-25 also will be closed to all traffic to maintain safety and free-flowing traffic while the ramp detour is in place. 

This work follows the four-day interchange closure (opened Saturday, Aug. 21) and the extended closure of the northbound I-25 ramps (opened Monday, Aug. 23) at County Line Road.

About the Project

CDOT is improving 18 miles of I-25 between Monument and Castle Rock by widening the highway from two to three lanes in each direction. The new lane will operate as an Express Lane, allowing motorists the choice of taking the Express Lane for a faster, more reliable travel time in exchange for a toll. Express Lanes will be free to vehicles with three or more people and motorcycles. All travelers will have the choice of taking the general-purpose lanes for free.

The $419 million project also includes shoulder widening, rebuilding bridges, new wildlife crossings, resurfacing with new pavement, improving operations with a southbound I-25 truck climbing lane near Monument and modernizing technology. Project completion is scheduled for November 2022.
