Full closure of eastbound South Academy Boulevard
Thursday, April 25, 7 p.m. to 6:30 a.m.

Full closure of westbound South Academy Boulevard

Westbound South Academy Boulevard traffic will be diverted north on I-25 to Lake Avenue/South Circle Drive (exit 138), where they will turn around and re-enter I-25 south to South Academy Boulevard.

The speed limit in this area has been reduced to 60 MPH. Traffic delays of 10-15 minutes are expected and motorists are urged to use extra caution while traveling in the area. Fines will be doubled through the construction zone.

There will also be a southbound I-25 mobile right lane closure on Monday, April 22, 7 p.m. to 6 a.m. between South Academy Boulevard and Santa Fe Avenue to allow crews to perform signage work.

On Thursday, April 25, 7 p.m. to 6 a.m., and Friday, April 26, 8 p.m. to 9 a.m., there will be a southbound I-25 right lane closure south of South Academy Boulevard (mile points 134.5 to 133.5) and south of Mesa Ridge Parkway.

There will be ongoing southbound U.S. 85/87 right and auxiliary lane closures under the South Academy bridge from Sunday, April 22 at 12 a.m. through Friday, April 26 at 7 p.m. to allow crews to install drainage pipe across the roadway. Motorists are urged to use caution traveling through the area.

Due to gas line work in the area, north- and southbound U.S. 85/87 left lane closures under the South Academy Boulevard bridge have been rescheduled for Saturday, April 27, 4:30 a.m., through Tuesday, May 7, to allow crews to continue drainage pipe installation across the roadway.

Also, on Friday, April 26, 7 p.m. through Saturday, April 27, 4:30 a.m., there will be north- and southbound U.S. 85/87 alternating lane closures under the South Academy Boulevard bridge to allow crews to place lane striping for a temporary new configuration which will consist of a single lane closure in both the north- and southbound directions.

Additionally, there is a tentative plan to close the southbound South Academy Boulevard off-ramp to U.S. 85/87 on Friday, April 26, 7 p.m. to Saturday, April 27, 12 p.m. for installation of drainage pipe across the roadway. A detour will be in place:

Traffic intending to exit southbound South Academy Boulevard to US 85/87 will continue west and turn right onto Venetucci Boulevard, travel north and turn right onto the B Street overpass, and immediately turn right onto the CanAm Highway.

Bradley Road under the South Academy Boulevard bridge will be reduced to one lane of alternating traffic on Tuesday, April 23 and Wednesday, April 24, 8 a.m. to 4 p.m., with flaggers and signage to assist travelers in navigation through construction to allow crews to perform work on new bridge pier caps. This closure is necessary for the safety of the traveling public. Expect minor delays. In case of inclement weather, a contingency has been scheduled for Wednesday, April 24 and Thursday, April 25.

A shift to a temporary on-ramp for drivers entering northbound South Academy Boulevard from U.S. 85/87 is ongoing as crews will perform work on roadway, drainage and utilities in the area. The ramp lane width will be reduced to 12 feet, and speeds will be reduced to 30 MPH. This closure will be in effect approximately 5-6 months.

Motorists are advised to use caution at all entrance ramps as merge lengths have been shortened. In particular, motorists should be prepared to stop on the US 85/87 on-ramp to eastbound South Academy and the Bradley Road on-ramp to eastbound South Academy since merge area is greatly reduced. Work crews are installing signage and flashing beacons to alert traffic to the reduced merge lengths.

These closures are weather dependent and subject to change.

Project Overview

Interstate-25 - Safety and Efficiency Improvements

The improvements to I-25 addressed in this project are located along an approximately 7.5-mile segment of south I-25 beginning at South Academy Boulevard and extending to the Santa Fe Avenue (U.S. 85/87) exit at Fountain (MP 128), which exits to Gate 19 of Fort Carson. The project includes:

Replacement of two bridges crossing over South Academy Boulevard.

Widening of both inside and outside shoulders and installing safety improvements.
Concrete surface treatment overlay to provide an improved riding surface.
Installation of median barrier.
Rehab and widening work on four bridges.
Installation of an I-25 southbound deceleration lane at the interchange with Colo. 16.

South Academy Boulevard Widening Project

The improvements to South Academy Boulevard in this project are located on South Academy Boulevard at the southern mile and a half of this arterial road from the I-25 interchange, crossing U.S. 85/87, and continuing to the road's approach to Milton Proby Parkway (which connects to Powers Boulevard/Colo. 21). Construction focuses on widening an approximately 1.5-mile section of South Academy Boulevard from two lanes to three in each direction to alleviate recurring congestion. The project includes improved drainage facilities, lighting, striping, and expanded shoulders, modified merge lanes, sound walls and bridgework. The project is expected to be complete by early 2026. This project is managed by El Paso County.

Safety Benefits

CDOT conducted a safety assessment for the corridor to evaluate the magnitude and nature of safety problems and analyze the causes of crashes. These transportation improvements are mitigation measures to reduce crashes, improve infrastructure, and address physical deficiencies that contribute to crashes in the corridor. Over the next 20 years, the project is estimated to result in fewer deaths, injuries and crashes on the four MAMSIP corridors.
