Avenue 12 Overpass


Construction is currently underway on an overcrossing that will take Avenue 12 traffic over future high-speed and existing BNSF rail lines outside the town of Madera, eliminating the need for the existing at-grade crossing.


On the north side of Avenue 12 a little east of Madera Community College.


Excavation work for a new Avenue 12 alignment continues in Madera County east of Madera Community College. Two bridges will be connected by an earthen embankment for a crossing that will allow Avenue 12 traffic to cross over the future high-speed rail line and the freight line further to the east. Approximately 500,000 cubic yards of fill dirt is being trucked to the site to build up the embankment, and additional dirt is currently being trucked into the east of the BNSF tracks. Crews are constructing the abutment wall on the west side of the tracks, while on the east side, an electrical pole is being relocated and then excavation and a drill rig will move in to begin work on the abutment substructure for that side.


Construction began in February 2017 and is expected to be finished in mid-2018.
