The project included the creation of an 250 ft. overpass over the Union Pacific railroad line between Hutchins and Stockton streets, the addition of one driving lane in each direction from Highway 99 to Hutchins Street, the installation of soundwalls, sidewalks and center median, and landscaping.
Construction began in April 2016, with an expected completion time of 18 months. The two south lanes were opened to two-way traffic in May 2017. In November 2017 both sides of the bridge were opened to drivers through one eastbound and one westbound lane. The project was opened to its final, four-lane configuration in December 2017.
