Colorado Department of Transportation and SEMA Construction are continuing to work on I-25 between South Academy and Santa Fe Avenue in Fountain. Current work includes the widening of the Clover and Dry Wash Bridges, constructing the substructure for the I-25 bridges over South Academy and hauling dirt and building up the embankment for the I-25 roadway.

There will be alternating left- and right-lane closures on northbound and southbound I-25 Sunday and Monday night so crews can install advance warning signs, move crane from Dry Wash Bridge to South Academy Boulevard, and perform maintenance work on the I-25 roadway. There will also be a right-lane closure on northbound I-25 on Wednesday and Thursday nights to remove striping. Commuters will encounter these closures between MP 127 and 135.

There will be right shoulder closures on northbound I-25 on Tuesday, Wednesday and Thursday during daytime hours, so crews can perform survey work in the area. Also, during the evening hours from Wednesday through Thursday (March 16-17) travelers can expect to see increased truck traffic at night as crews will be hauling embankment at night into the median. No lane closures are needed for the embankment haul.

On the bridges over South Academy, crews will be driving pile on the north abutment and drilling caissons in the median of South Academy and beginning work on the permanent retaining wall, for the structure.

Commuters will see increased construction at the Dry Wash and Clover Ditch bridges as crews begin the forming and pouring of concrete for the new footers and piers.

Charter Oak Ranch Road

Flagging operations will continue on Charter Oak Ranch Road with intermittent shoulder closures Monday through Friday, from 7 a.m. to 5 p.m. This will allow crews to safely continue their work on the drainage system and dirt work. Nighttime flagging operations will take place Wednesday, March 16, to allow trucks to move safely around the job site. Please use extra caution when driving through the work zone.

Construction schedules are weather-dependent and subject to change.

Motorists are encouraged to register for text alerts by Texting MAMSIP to 888-970-9665

A Courtesy Patrol will be driving the work zone and will respond to incidents when notified. Hours of operation are 7 a.m. to 6 p.m., Monday through Friday and holidays.

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 the corridor beginning at South Academy Boulevard and extending to the Santa Fe Avenue (CO 85/87) exit at Fountain (MP 128), which exits to Gate 19 of Fort Carson.

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 for this 7.5-mile segment;

Installation of median barrier the entire length of this corridor;

Rehab and widening work on four bridges along the corridor, and

Installation of I-25 Southbound deceleration lane at the interchange with Colorado Highway 16.

Safety Benefits

The safety enhancements relate to the potential to reduce crashes, improve infrastructure, and address physical deficiencies that contribute to crashes in the corridor. CDOT conducted a safety assessment for the corridor to evaluate the magnitude and nature of safety problems and analyze the causes of crashes.

The proposed transportation improvements are mitigation measures to reduce crashes and improve safety in the corridor. It is estimated that the delivery of the MAMSIP project will, over its' twenty years of operation, result in fewer deaths, injuries, and crashes on the four corridors the project addresses.
