112-Year-Old Colorado Bridge to Be Replaced

March 29, 2023
The replacement is expected to cost $22.3 million

The Alameda Bridge that stands over the South Platte River in Colorado is set to be replaced by the Colorado Department of Transportation (CODOT). The 112-year-old structure is the oldest in the Centennial State. The bridge replacement is expected to cost $22.3 million.

The project details will include building a multi-modal corridor by modifying the West Alameda Avenue intersection at South Santa Fe Drive, removing South Platte River Drive between Alameda and Cedar Street, and diverting traffic to a widened South Lipan Street, north of Alameda.

CODOT is also looking to reconstruct the South Platte River Trail with improved sight distances, including a 12-foot concrete trail, a four-foot finely crushed stone trail, and three-foot vegetated shoulders for an overall trail width of 22 feet. An on-street bike lane is in the plan, along with installing a pond, and improving sidewalks on the north and south part of the bridge.

During construction, two lanes will remain open in each direction.

Demolition work is expected to start in the spring which will result in closures of the structure.

There is already a closure at Lipan Street in place, with plans to build it out during the first phase of construction.

The South Platte River Trail will remain open but detoured around the construction zone where it crosses under Alameda Avenue. The trail will close intermittently during bridge demolition.

Construction is expected to be completed in 2024.
