The North Presa Street North Bridge is one of a few similar Warren polygonal pony trusses in San Antonio. The bridges are unusual in that while the ends of the truss are inclined, the center section has a flat top chord. Since North Presa Street crosses the river at a river bend, the bridge is skewed and has an approach thru girder span. The bridge is also unusual that the road deck does not fill the space between the truss lines.
