  • There are currently 13 active construction sites within Construction Package 1 from Avenue 19 in Madera County to East American Avenue in Fresno County.
  • Construction Package 1 work is being led by the design-build team Tutor Perini/Zachry/Parsons (TPZP).
  • Right-of-way acquisition, utility relocation, abatement, demolition activities and continued development of design is ongoing.


  1. Fresno River Viaduct:
  • Raymond Road to Watson Street, crossing SR 145 and the Fresno River in Madera County
  • First free standing structure to be constructed that is part of the nation’s first high-speed rail system.
  • Approximately 1,600 foot aerial structure that will carry high-speed trains over SR 145 and the Fresno River
  • Work began in June of 2015 and was completed earlier this year.
  • Height: 20-feet
  • Diameter: 10-feet
  • Depth: 70-80 feet


  1. San Joaquin River Viaduct
  • San Joaquin River on the east side of State Route 99, just north of Herndon Avenue in north Fresno.
  • The San Joaquin River Viaduct is an approximately 4740-foot structure that will span the San Joaquin River in north Fresno and the Union Pacific tracks parallel to State Route 99.
  • This viaduct will feature arches representing the northern gateway into Fresno.
  • It will also feature a pergola structure in order to cross over the top of the Union Pacific tracks.
  • Height: 20-feet
  • Diameter: 10-feet
  • Depth: 70-80 feet


  1. Fresno Trench/ State Route 180
  • Two-mile trench between Olive and Belmont Avenues that continues to Stanislaus Street in downtown Fresno.
  • The Fresno Trench is the first section of the alignment to be built below-grade.
  • The trench will reach a depth of approximately 40-feet that must pass beneath a Union Pacific rail spur, Dry Creek Canal and State Route 180 (SR 180).
  • Construction beneath SR 180 will be a top-down project where crews will dig from the top of the SR 180 to a depth of approximately 70-feet, construct a portion of the tunnel and then reconstruct the highway.
  • SR 180 requires significant lane shifts, but will not require lane closures.


  1. Tuolumne Street Bridge
  • Tuolumne Street between F Street and Broadway Street in downtown Fresno.
  • The Tuolumne Street Bridge heading into downtown Fresno was demolished earlier this year and was rebuilt to accommodate the high-speed rail system.
  • The bridge was rebuilt so that the highest point of the bridge is shifted to the west creating clearance for high-speed trains and will also accommodate two-way traffic.
  • Demolition began in January of 2016. The bridge opened August 4, 2017.


  1. Cedar Viaduct
  • Parallel to State Route 99 near North and Cedar Avenues in south Fresno.
  • The Cedar Viaduct marks the southern end of the high-speed rail line through Fresno, extending over State Route 99 and North and Cedar Avenues.
  • The 3,700- foot viaduct will feature signature concrete arches and allow high-speed trains to travel over State Route 99 and North and Cedar Avenues.
  • Drilling and concrete foundation work started in 2016 and now has over a dozen completed columns and a standing bridge deck that can be seen from SR 99.
  • Height: 30-40 feet
  • Diameter: 10-feet
  • Depth: 70-80 feet
