Ramps closing for several weeks at County Line Road

July 9, 2021 - The northbound off- and on-ramps at I-25 and County Line Road near Monument (Exit 163) closing for six weeks

Douglas/El Paso Counties – The northbound off- and on-ramps at Interstate 25 and County Line Road near Monument (Exit 163) are closing for about six weeks, allowing crews to remove the aging ramps and place them into a new configuration, as part of the reconstruction of the interchange.

Both ramps close at 8 p.m. on Sunday, July 11, and remain closed through mid-August.

Detours

For access to northbound I-25 from County Line Road, motorists will head south on I-25 and use the CO 105 interchange (exit 161) to go north. To access County Line Road from northbound I-25, motorists can continue north on I-25, turn around at the Greenland Road interchange (exit 167) and head southbound on I-25 to County Line Road.

The project has coordinated with local emergency responders to maintain access while the ramps are closed. The County Line Road Bridge over I-25 also will remain open to traffic. 

Construction schedules are weather-dependent and could change. Current information is available on i25gap.codot.gov or by following the project on Facebook @I25SouthGapProject.

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.

Project Information

About the I-25 South Gap 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.
