Travel Advisory

October 9, 2023 - Southeastern Colorado - Requires a 21-day full closure on US 350

Otero County —­­ The Colorado Department of Transportation and CapitalTezak JV will implement a 21-day closure with an approved detour beginning at 9 a.m. on Monday, Oct. 23 for replacement of a bridge structure located on U.S. Highway 350 southwest of La Junta. The structure, originally built in 1935 and is structurally deficient and obsolete, will be replaced with a concrete box culvert (CBC). The closure will be complete by 9 a.m., Monday, Nov. 13.

The bridge replacement work will occur on US 350 between mile posts 59.5 and 72. The structure, which spans over the Otero Ditch Canal is located three miles southwest of the US 50 junction in La Junta. The purpose of the 21-day closure is to limit construction duration, increase crew and motorist safety and minimize impacts to the Otero Ditch Canal. A detour will be in place.

During the extended closure, US 350 will be closed. All traffic will utilize CO 71 and CO 10. County Road Y and access to local properties will remain open.

Project Information

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.
