This orthotropic deck was the first in the United States on a major bridge. Over 40 materials were laboratory tested as candidates for original riding surface of the orthotropic portion of the San Mateo Bridge. The most promising were field tested on smaller orthotropic bridges. An epoxy asphalt concrete (EAC) was chosen.

Engineers define an orthotropic deck as one that consists of steel plates supported by ribs underneath, overlain by an integrated wearing (driving) surface. An orthotropic deck is a collage of steel plates welded together with a flat, solid steel deck stiffened by a grid of deck ribs welded to framing members like floor beams and girders.
