Multi-day closure ahead at County Line Road interchange
Travel Advisory
DOUGLAS/EL PASO COUNTIES – The reconstruction of the County Line Road Interchange requires a four-day closure of the ramps and bridge to complete the placement of permanent pavement.
WHAT: Full closure of the County Line Road interchange (Exit 163), including the bridge over Interstate 25, both intersections and I-25 on- and off-ramps.
WHEN: 8 p.m. Monday, Aug. 16, to 5 a.m. Saturday, Aug. 21
DETOURS: For local and I-25 access, use the Colorado Highway 105 interchange (exit 161).
Construction schedules are weather-dependent and subject to change.
In addition, the newly constructed northbound I-25 ramps at County Line Road are scheduled to reopen to traffic at 5 a.m. on Monday, Aug. 23. Both were closed for six weeks.
Drivers generally will have access across the County Line Road bridge for the remainder of construction. However, some remaining work will require overnight closures of the bridge and ramps in August and September.
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.

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 and modernizing technology. Project completion is scheduled for 2022.
