The California High-Speed Rail Authority announced on May 23, 2025 the completion of another high-speed rail grade separation in Fresno County. Central Avenue is now open to traffic and is the fourth high-speed rail structure to be completed this year. Construction began in 2023 at the Central Avenue Grade Separation, which was built by contractor Tutor Perini/Zachry/Parsons (TPZP). Located in south Fresno between Maple and Cedar avenues, the overpass eliminated the at-grade railroad crossing and will now take traffic and pedestrians over the BNSF railroad and future high-speed rail tracks.

The Central Avenue Grade Separation spans 432 feet long, more than 42 feet wide, and is designed for two-lane traffic and pedestrian access. The overcrossing is comprised of 20 pre-cast concrete girders, 3,700 cubic yards of concrete, and 820,000 pounds of reinforced steel.

Construction is nearly completed at the Central Avenue Grade Separation in Fresno County.  Recently, crews striped the roadway and recently installed light poles and handrails. With final touches underway, the grade separation will open to traffic this spring. When complete, it will span 432-feet in length, more than 40-feet wide, and will take traffic and pedestrians over the high-speed rail and BNSF railroad tracks safely.

Central Avenue closed to traffic in October to begin construction on an overpass. At Central, crews have relocated the electric distribution lines and closed the portion of Central Avenue roadway from Cedar to Maple Avenues removing the current BNSF At-grade crossing to begin construction of the new separated grade crossing at that location. Construction will be continuous

Crews have been hard at work the last few months at Central Avenue in Fresno County. Rebar and concrete have been placed to form the abutment wall on the west side of the structure. The columns are formed at each of the bents and crews are now working to tie rebar to form the bent caps. PG&E utility relocation in the area was also completed in March, which will allow crews to begin building embankment walls and the embankments of the structure. When completed, the Central Avenue Grade Separation will be 432-feet long, more than 40-feet wide and will take traffic over the high-speed rail and BNSF tracks.
