Superstructure work continues at the Avenue 15 ½ Grade Separation in Madera. In April, all 16 girders were placed and in May, crews set more than 117 deck panels for the top of the structure. Ironworkers continue to tie deck reinforcement and crews continue to place deck concrete. When complete, the Avenue 15 ½ Grade Separation will span 468-feet long, 40-feet wide and will take traffic over BNSF and future high-speed rail lines.
