S. Dahlia Street Bridge Replacement

Project Overview

The existing bridge on S. Dahlia Street over the High Line Canal needs to be replaced. The Denver Department of Transportation and Infrastructure (DOTI) will remove the deteriorating bridge, which was constructed in 1952, and install a large concrete box culvert as part of the Bridge Asset Management Program. The road over the new box culvert will match the existing configuration of one lane in each direction with sidewalks on both sides. The sidewalk on the bridge will be widened to six feet.

Traffic Update: Week of June 15-21

Travel Impacts

During construction, S. Dahlia Street will close between Highline Place and E. Eastman Avenue. Residents will still be able to use S. Dahlia Street to access their homes from either side of the bridge. Through vehicle traffic will be detoured as follows:

• Northbound travelers will turn left on Hampden Avenue, right on Colorado Boulevard and right on Cornell Avenue.
• Southbound travelers will turn right on Yale Avenue, left on Colorado Boulevard and left on Hampden Avenue.

The High Line Canal Trail will close just west of S. Dahlia Street. Trail users will detour along the north edge of Mamie D. Eisenhower Park. Vehicle parking along the north edge of the park will be restricted to accommodate the trail detour.

Sidewalks will close on S. Dahlia Street near the bridge. The pedestrian detour uses E. Eastman Avenue, Forrest Street, and the footbridge over the High Line Canal to connect to the High Line Canal Trail to return to Dahlia Street.
