Austin's main roads follow the line where the flat Blackland Prairie meets the hills to the west. I-35 runs north-south straight through the center, past downtown and the University of Texas, and carries traffic toward Round Rock, Georgetown, Kyle and San Antonio. MoPac, Loop 1, parallels it on the west side, and SH 130 bypasses the whole city to the east as a tollway. US 183 angles northwest toward Cedar Park and Leander and loops around the east side toward the airport, SH 71 and Ben White Boulevard cross the south side, US 290 heads west into the Hill Country and east toward Houston, and Loop 360 winds through the western hills.
I-35 through downtown is one of the most congested stretches of road in Texas, and MoPac backs up every weekday too. A breakdown on either one is slow to clear and dangerous to sit in. For a mobile mechanic, the better news is that most neighborhoods are reached on surface streets like Lamar, Burnet, Congress, Riverside and Parmer, and a driveway in Hyde Park or Mueller, an office lot in the northwest tech corridor or an apartment complex in Riverside are often easier to reach than a shop.
Austin-Bergstrom International Airport sits southeast of downtown off SH 71, and its long-term and economy lots are common service locations. CapMetro runs city buses and the MetroRail line from Leander into downtown. The University of Texas campus, the State Capitol, the Dell Medical School and hospital district next to campus, and the big tech campuses north of the city all add heavy daytime parking demand. During big festival weeks downtown, garages fill and streets close, so meeting at home or at a lot outside the core is usually simpler.
