Eastbound Capitol Corridor train #526 starts across the Yolo Causeway, midway between Davis and Sacramento, California. CDTX 2011 (EMD F59PHI) is pushing.
Officially, the "Yolo Causeway" is the highway viaduct which carries Interstate 80 over the Yolo Bypass, although railroaders also often refer to this adjacent railroad line (part of the Union Pacific Martinez Subdivision) as "the Causeway." This combination of trestles and rock fill is approximately 3 miles long. The Yolo Bypass is used as an overspill area to help prevent the Sacramento River from flooding much of the metropolitan Sacramento area during periods of high rain or snow runoff--as can be seen above, it is currently serving its purpose. During dry periods, much of it is used as farmland.
