State Route 905 (SR 905), also known as the Otay Mesa Freeway, is an 8.964-mile-long (14.426 km) state highway in San Diego, in the southwestern part of the U.S. state of California. It connects I-5 and I-805 in San Ysidro to the Mexican border at Otay Mesa. The entire highway from I-5 to the international border is a freeway with a few exits that continues east from the I-805 interchange before turning southeast and reaching the border.
SR 905 formerly followed Otay Mesa Road, which had been in existence since at least 1927. Before it was SR 905, the route was first designated as part of SR 75, before it was redesignated as SR 117. The freeway was completed between I-5 and Otay Mesa Road in 1976. The border crossing opened in 1985 after several delays in obtaining funding for construction on what would become SR 905. After becoming SR 905 in 1986, the highway was converted to first an expressway in 2000 and then a freeway in 2010 and 2011. Plans are for this highway to eventually become Interstate 905.
