Extended closure of the County Line Road interchange near Monument for bridge work

June 21, 2021 - Central/Eastern Colorado - Detour using CO 105 interchange; sign up for text alerts by texting I25GAP to 21000

DOUGLAS/EL PASO COUNTIES –The Colorado Department of Transportation and contractor partner, Kraemer North America, are reconstructing the aging County Line Road bridge near Monument as part of the I-25 South Gap project. Motorists can anticipate a full, four-day closure of the I-25 ramps and bridge at County Line Road (exit 163) as crews work to join the existing roadway with the newly constructed ramps and bridge structure. 

After the four-day closure, crews will switch traffic to the newly constructed structure, then demolish and build the remainder of the bridge in the middle. During the remainder of construction, drivers will generally have access across the County Line Road bridge, though some overnight closures will be necessary for demolition. 

Construction schedules are weather-dependent and could change. Current information is available on i25gap.codot.gov or by following the project on Facebook (@I25SouthGapProject). To receive text alerts, text I25GAP to 21000.

About the County Line Road Bridge

The County Line Road bridge (circa 1964) is one of five bridges being replaced as part of the 18-mile I-25 South Gap project between Monument and Castle Rock. The County Line Road bridge will double in size to accommodate one through-lane and one turn-lane in each direction, and wider shoulders on each side. Major bridge reconstruction is expected to be complete by the end of 2021.  Construction of the entire 18-mile corridor, including the surrounding County Line Road bridge area, is slated for November 2022. The project is on-schedule and on-budget. Full resolution of the graphic below is attached.

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 $419.5 million project also includes shoulder widening, rebuilding bridges, new wildlife crossings, resurfacing with new pavement and modernizing technology. Project completion is scheduled for 2022.
