The Grade Separation Project

The McKinley Avenue and Golden State Boulevard grade separation project is located between State Route 99 and West Avenue in Fresno. When complete, the grade separation will serve as a four-lane roadway, spanning 402 feet long and more than 78 feet wide. 

The bridge will also have pedestrian access and bike lanes improving safety for residents in the area. The grade separation is being built by contractor Tutor-Perini/Zachry/Parsons.

Progress on High-Speed Rail in California

The Authority has begun work to extend the 119 miles currently under construction to 171 miles of future electrified high-speed rail from Merced to Bakersfield. 

The Authority also has full environmental clearance on 463 miles of the high-speed rail program from the Bay Area to downtown Los Angeles.

There are more than 30 active construction sites and nearly 50 completed structures in California’s Central Valley. Since the start of high-speed rail construction, the project has created more than 14,000 construction jobs, a majority going to residents of the Central Valley.

In addition, the Authority is committed to small businesses playing a major role in the build out of the project. A total of 875 certified small businesses have worked on the high-speed rail program statewide, with 229 of those certified small businesses residing in the Central Valley.
