Girders have been set for the single span bridge at Avenue 8, which crosses the high-speed rail alignment east of State Route 99 in Madera County. The block wall leveling pads have been poured and fill-dirt is being compacted as the MSE blocks are being set for the retaining walls. Crews are currently forming and installing steel for the bridge diaphragms. Diaphragms stabilize the girders permanently and help improve load sharing of the bridge elements.
