I-5 and I-15 are the main north-south interstates through the area, with I-5 marking the western boundary of the area and I-15 running through the central and eastern parts of the area. Additionally, SR-163 and I-805 connect the area to the south, with SR-163 continuing through Mission Valley to Downtown and I-805 heading through Mission Valley and the Mid-City area down to I-5 near the US-Mexico border. SR-52 is a main east-west highway, running from near La Jolla past Clairemont and Kearny Mesa out to Santee. Further north, SR-56 runs between I-5 near Del Mar and I-15 near Poway.
The Metropolitan Transit System MTS (http://www.sdmts.com/home1.asp) runs buses throughout San Diego, but bus service in these parts is often infrequent. The North County Transit District NCTD (http://www.gonctd.com/) operates bus routes through northern San Diego County and a couple of those routes serve parts of Northeastern San Diego, including Route 386 which connects Escondido to the San Pasqual Valley and the Wild Animal Park. The COASTER (http://www.gonctd.com/), a regional rail line that runs along the coast between Downtown San Diego and Oceanside, stops at Sorrento Valley. From there, a number of shuttle routes connect the station to the immediate area.
