Abstract
An overfilled, pre-cast reinforced concrete arch bridge for supporting one pathway above a second pathway in which the projections of the pathways intersect at an oblique angle. The bridge includes a plurality of identically shaped arch elements that are offset from each other to form a staggered orientation whereby a skewed bridge is formed without specially shaped arch elements. Cover elements can be used to prevent migration of soil or water into the bridge and various forms of arch elements can be used in the bridge.
