Davis Avenue Overcrossing

At Davis Avenue, crews recently post-tensioned the bridge and are now working on the backwalls. Ironworkers have tied rebar and crews have recently placed concrete to form the barrier rails on top of the structure. The roadway will be paved in the coming weeks.

At Davis Avenue, crews are working on the mechanically stabilized earth (MSE) coping, the portion of the retaining wall that hides the top edge of the facing panels. Next, crews will proceed with installing falsework for the future overcrossing that will take traffic over the high-speed rail lines.

Over the last month, crews continue to haul nearly 400 truckloads of dirt a day to form the slopes of the Davis Avenue Grade Separation. Crews are now setting panels to form two mechanically stabilized earth (MSE) retaining walls and backfilling the walls with dirt. The Davis Avenue Grade Separation will allow traffic to cross over the high-speed rail alignment.

In Fresno County, bulldozers, graders and haul trucks are working simultaneously to install high-speed rail embankment north of Davis Avenue. As the embankment haul takes place, street sweepers and water trucks are in operation to keep the roads clear of debris.

Just west of State Route 43 in south Fresno County, crews conduct geotechnical analysis on test piles for a future overcrossing for Davis Avenue. The test piles are driven into the ground and then subjected to forces to see how the soils react. Designers will use the data collected to determine how to construct the future overcrossing that will take Davis Avenue traffic over the high-speed rail line.
