County Line Road near Monument ramps closing for several weeks at County Line Road – ramps close at 8 p.m. on Sunday, July 11, and remain closed through mid-August.

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.

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).

VEHICLE LENGTH RESTRICTIONS BEGIN FRIDAY, JULY 2, AT COUNTY LINE ROAD 

Due to ongoing bridge construction, left turns will be restricted for vehicles over 35 feet:

1. No left turns on the bridge from northbound I-25 to westbound County Line/Palmer Divide Road
2. No left turns on the bridge from southbound I-25 to eastbound County Line/Palmer Divide Road

These restrictions are expected to remain in effect throughout bridge construction for the safety of crews and the traveling public. Please use CO 105 (exit 161). Once the bridge opens, watch for lower speeds and narrower lanes.

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.
