Fort Collins – The Colorado Department of Transportation is nearing completion of work on the new Prospect Road bridge over I-25. Roadway tie-ins from the new bridge to the existing roadway be completed during a weekend closure of Prospect Road from July 16-19.  Once tie-in work is completed, Prospect Road will open in its new configuration with two through lanes in each direction, center turn lanes, and a bike and pedestrian multi-use path in each direction.
