A new Colorado Department of Transportation project will replace the oldest bridge on the state highway system with a new structure that offers safety improvements not just for motorists but for bicyclists and pedestrians as well.

The Alameda Avenue/Colorado Highway 26 Bridge over the South Platte River was originally constructed in 1911 and subsequently widened in 1966, Colorado DOT noted in a statement.

The $22.3 million project – scheduled for completion by the end of 2024 – also aims to enhance multimodal transportation options along and around the new bridge.

For starters, the agency said the bridge is part of an overall effort to build a “multimodal corridor” that includes constructing an on-street, two-way protected bike lane on the north side of Alameda between South Lipan Street and South Kalamath Street with a connection to the South Platte River Trail.

Construction will add 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 to improve pedestrian and bicycle access, along with new sidewalks on the north and south side of the bridge.

Finally, the project includes the installing a water quality pond to manager storm-water runoff around the new bridge structure.
