County Line Road Bridge

County Line Road Impacts near Monument

6-Week Closure of the Northbound I-25 Ramps at County Line Road

Beginning at 8 p.m. on Sunday, July 11, and lasting six weeks, the northbound I-25 off- and on-ramps at the County Line Road interchange (exit 163) near Monument will be closed for reconstruction. This work is part of the County Line Road bridge replacement and I-25 widening. Access across the County Line Road bridge will remain open! 
 
For access to northbound I-25, head south on I-25 and use the CO 105 interchange (exit 161) to turn back north. For access to County Line Road from northbound I-25, continue north on I-25, turn around using the Greenland Road interchange (exit 167) and use the southbound I-25 off-ramp to County Line Road.

Turning Restrictions on County Line Road Bridge

The County Line Road bridge (exit 163) has been closed for bridge construction. Once open, there will be turning restrictions for vehicles over 35 feet long beginning July 2:

  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 last 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 more narrow lanes. 

In spring 2021, the Colorado Department of Transportation and contractor partner Kraemer North America will begin major reconstruction of the County Line Road bridge in Monument as part of the I-25 South Gap project. The County Line Road bridge will double in size, and accommodate one through-lane and one turn-lane in each direction, as well as shoulders on each side of the bridge.

For most of construction, access across the County Line Road bridge will be maintained.

County Line Road Bridge Final Alignment

Construction Approach

The bridge will be built in two phases. First, crews will build the outside lanes of the bridge. Once those lanes are built, they will shift traffic to the new bridges so they can demolish the existing bridge structure, reconstruct it  and then connect it to the new outside lanes. This phasing will allow for crews to maintain traffic on the bridge while keeping crews safe.

Traffic Impacts

Improvements to the County Line Road bridge will fix sight distance issues on the ramps, upgrade aging infrastructure (built in 1964) and improve County Line ramp acceleration and deceleration lanes. Impacts for this work include:

  • Flaggers and increased truck traffic on the County Line Road bridge
  • Six-week closure of the northbound I-25 on- and off-ramps at County Line Road
  • Four-day closure of the County Line Road bridge, intersections and ramps
  • Periodic closures of County Line Road bridge and I-25, with ramp detours, for overhead bridge work

Construction Timeline

Major reconstruction of the County Line Road bridge is expected to be complete by the end of 2021. Construction of the 18-mile corridor remains on-time for completion in November 2022. All construction activities are weather-dependent and subject to change.

Watch for narrower lane and shoulder widths, and always pay attention and follow posted speeds. Thank you for your patience during construction!
