Specifications include, but are not limited to: This project is to construct a bridge over the Colorado River between Laughlin, Nevada and Bullhead City, Arizona. The project includes an approach roadway in Nevada from the Needles Highway to the Colorado River Bridge, an approach roadway in Arizona from the western terminus of the Bullhead Parkway, west of the Mohave Highway (SR 95), and an intersection at Needles Highway to provide for turning lanes at the Nevada approach roadway. The approach roadway cross-section will include one lane in each direction and a 10 ft. wide multi-use path on the south side of the roadway. The Colorado River Bridge will be constructed to carry four ultimate lanes and a 10 ft. wide multi-use path. The bridge will be striped for an interim condition carrying two lanes (one lane in each direction) and a 10 ft. wide multi-use path.
