South Avenue is open to traffic! Last month, the Authority in collaboration with design-build contractor Dragados-Flatiron Joint Venture (DFJV), announced the completion of the South Avenue Grade Separation. Located between Cedar and Maple Avenues, the newly constructed overpass allows traffic to travel over the existing BNSF Railway and future high-speed rail lines. It is one of 36 grade separations being built in Construction Package 2-3 to improve safety along the high-speed rail alignment. The South Avenue Grade Separation spans nearly 390 feet and is 40 feet wide.
