Both directions of I-25 at Exit 11 south of Trinidad will be closed entirely on March 31 and April 1 in order to pour a concrete bridge deck

LAS ANIMAS COUNTY – Beginning at 3 a.m. and continuing until approximately 10 p.m. Thursday, March 31 and Friday, April 1, the Colorado Department of Transportation will implement a complete closure of both directions for Interstate 25 at Exit 11, south of Trinidad. Shutdowns are necessary while crews pour a concrete deck onto the new bridge structure.

All affected traffic will be diverted from I-25 heading north and south at the outer slopes to Exit 11 (see map) to bypass the closure. Uniformed law enforcement officers, tie-downs and signs will be present to alert motorists to the closure and direct traffic from Exit 11 to the ramps of Exit 11 to re-enter I-25.

effects of travel

While I-25 is closed at Exit 11, the following effects can be expected:

  • I-25 going north and south at Exit 11 will be completely closed on Thursday, March 31 and Friday, April 1
  • The closure will last from about 3 AM to 10 PM every day
  • Traffic will be diverted to Exit 11 ramps and back to I-25 via ramps
  • In case of bad weather, work will be rescheduled and closed
  • Minimal effects on distance and short delays can be expected
  • Exit 11 on I-25 is located at Mile Point 11, or 11 miles from the New Mexico/Colorado border
  • Motorists must follow signs and posted speed limits and be careful as slopes are also subject to temporary detours.
  • All construction schedules are weather based and subject to change.

work in progress

CDOT and contractor Flatiron Construction are building a new bridge about 100 feet south of the existing structure. Closures on I-25 are necessary to accommodate an entire concrete bridge deck pouring onto the new structure.

The new bridge is part of the I-25 Exit 11 Interchange Improvement project that began in mid-July 2021. The project is designed to improve infrastructure, upgrade facilities, add safety features, and improve access to Fishers Peak and area destinations. Work includes replacing the bridge, constructing ramp junctions, and constructing new roundabouts on the east and west sides of the intersection to improve traffic flow, add pedestrian facilities, and improve access to the port of entry. Work is being carried out in four phases with an expected completion date of late December 2022.
