Extended overnight lane closures along I-25 between Monument and Larkspur

Travel Advisory

September 28, 2020 - Central/Eastern and Southeastern Colorado - Additional impacts and delays nightly Sept. 30 - Oct. 4

DOUGLAS/EL PASO COUNTIES – Drivers along northbound Interstate 25 between Monument and Larkspur can expect delays from extended closures over several nights this week as crews install new drainage pipes underneath the interstate.  This work is necessary as part of the I-25 South Gap project. 

As part of the 18-mile I-25 South Gap project, crews will replace 9 miles of drainage pipes. Crews have already installed more than 7 miles of new drainage pipe, and upcoming lane closures will allow crews to do more. Crews will remove the asphalt pavement, replace the pipes at a depth of up to 15 feet, and then re-pave with asphalt. 

16-HOUR OVERNIGHT SINGLE LANE CLOSURES ON northbound I-25

  • There will be a single lane closure along northbound I-25 about two miles north of Greenland Road from 6 p.m. Wednesday, Sept. 30, to 6 a.m. Thursday, Oct. 1.

  • There will be single lane closures extending up to 1.5 miles on northbound I-25 just south of Upper Lake Gulch Road on three occasions:

  • 6 p.m. Thursday, Oct. 1, to 10 a.m. Friday, Oct. 2

  • 6 p.m. Friday, Oct. 2, to 10 a.m. Saturday, Oct. 3 

  • 6 p.m. Saturday, Oct. 3 to 10 a.m. Sunday, Oct. 4

  • Drivers may see crews setting up cones and signs up to an hour prior to the expected start of the lane closure.

  • There are no alternate routes, so drivers should plan for an additional 20 minutes and stay the course on I-25. 

Other closures include:

14-DAY CLOSURE OF SKY VIEW LANE (TOMAH ROAD) ON-RAMP TO SOUTHBOUND I-25

Beginning at 5 a.m. on Monday, Oct. 5, and lasting for 14 days, the Sky View Lane (Tomah Road) on-ramp to southbound I-25 will be closed. This closure is required as crews connect the ramp to the new southbound I-25 lane alignment. Crews will also replace the drainage on this ramp during this closure.

For access to southbound I-25, motorists are asked to head north and use the Plum Creek Parkway on-ramp to southbound I-25.

NEW ALIGNMENT SOUTHBOUND AT PLUM CREEK 

As construction in the northern section of the project nears completion, crews will return the southbound I-25 lanes to their original alignment (three through lanes and one exit lane). This work will require a 12-hour single lane closure on southbound I-25 between the Wolfensberger Road and Plum Creek Parkway exits, and a closure of the southbound I-25 off-ramp to Plum Creek Parkway from 8 p.m. to 8 a.m. Thursday, Oct. 1. 

All work is weather-dependent and subject to change.

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