CDOT Reminds Travelers of Region 2 Bridge Bundle – West – Mountain Region

The Colorado Department of Transportation (CDOT) in collaboration with prime contractor CapitalTezak Joint Venture will implement a 21-day closure with a detour beginning April 17 for construction of two bridge structures located on US Highway 24 between Antero Junction and Hartsel.

If the project were to replace these structures under single-lane closures, construction would take approximately four months each structure. By having a 21-day closure, the construction schedule will be shortened by approximately four months and should be complete in three months.

These structurally deficient structures, located on US Highway 24 at Mile Points 227.1 and 229.5, were built in 1937 and will be reconstructed concurrently. Both structures will be replaced with single aluminum box culverts (ALBCs) with reinforced concrete footings and floor. For the safety of the traveling public these structures require a full replacement.

During the extended closure, all traffic will be detoured at the Colorado Highway 9 and US Highway 24 junction west of Hartsel and at the U Highway 24 and US Highway 285 junction also known as Antero Junction. Variable message boards, signs and construction devices will be present alerting motorists of the closure and detour route. The closure is part of the Region 2 Bridge Bundle Project that began in 2022.

Hours of Full Closure of US Highway 24

  • The closure will be in place from 8:00 a.m., Monday, April 17, and run continuously until approximately 5:00 p.m. on Sunday, May 7.
  • All construction schedules are weather dependent and subject to change.

Traffic Impacts & Detour Route

  • Use CO 9 to US 285.
  • Motorists can expect to add 25 miles and 30 minutes to travel times with the detour.
  • US 285 traffic will not be affected by the closure.
  • Lane closures and other traffic notices are posted weekly to
  • All construction schedules are weather dependent and subject to change.
  • Motorists are reminded to drive slowly and obey the posted speed limit.

Project Overview

Colorado is one of the fastest-growing states in the country, and with that growth comes strain on aging transportation systems that have significant consequences in the form of growing safety and mobility problems. The purpose of this project is to provide necessary improvements to 17 structures so motorists can be ensured that they are driving on more stable and up-to-date structures with life spans of 100 years.

The three rural highway corridors where structures are being replaced include:

Colorado Highway (CO) 9
US Highway 24
US Highway 350

Construction completion of the Bridge Bundle $43 million project is slated for late 2024.
