Otay Mesa, San Diego
Otay Mesa is a community in the southern section of the city of San Diego, just north of the U.S. Mexico border. It is bordered by the Otay River Valley and the city of Chula Vista on the north, Interstate 805 and the neighborhoods of Ocean View Hills and San Ysidro on the west, and unincorporated land of San Diego County on the north and east. Major thoroughfares include Otay Mesa Road/California State Route 905, Otay Valley Road/Heritage Road, Siempre Viva Road, and California State Route 125. South of the border between the United States and Mexico, the same region continues as a residential and industrial area called "Mesa de Otay", which is one of nine "delegaciones" (boroughs) of Tijuana Municipality.
