1943 Map of San Ysidro

USGS Topo · Published 1943

About this map

The United States Mexico international boundary defines the southern edge of this 1941 survey, where the Tia Juana River and Otay River cross the coastal plains of southern San Diego County. The landscape is a mix of early residential developments and agricultural infrastructure, with clusters of growth in Imperial Beach and San Ysidro. Transportation is dominated by the San Diego and Arizona Eastern River railroad and the Southern Pacific line, which connect the border region to San Diego Bay.
