#0250 Old Sites of Mission Santa Clara de Asis and Old Spanish Bridge
title: Site information: The site of the second location of the mission is at NE corner of Martin Ave and De la Cruz Blvd, Santa Clara 37.366782,-121.941147 The first location, based on the inscription on the cross, was likely somewhere at the very north end of the San Jose Airport near De La Cruz Blvd. It is hard to pinpoint, even though the distances are given so precisely. Part of the reason is I am not sure what bridge 37-64 is. In any case, nothing remains at either site that I know of, nor does the Old Spanish Bridge, which I assume crossed the Guadalupe River somewhere north of the Airport.
