Cincinnati's highways follow its valleys. I-75 runs north through the Mill Creek valley toward Dayton and south across the Ohio River on the Brent Spence Bridge into Covington, carrying I-71 traffic with it for the crossing. I-71 heads northeast through the east side toward Columbus, I-74 branches west toward Indianapolis, and I-471 crosses the river to Newport. I-275 makes a huge loop through three states, circling the Ohio suburbs, northern Kentucky and a corner of Indiana.
Inside that loop, the Norwood Lateral, SR 562, and the Cross County Highway link the north-south interstates, while Columbia Parkway, part of US 50, follows the river east toward Mount Lookout and Anderson, and River Road carries US 50 west. Fort Washington Way, the sunken freeway along the riverfront, ties I-71 and I-75 together downtown, and its tight lanes leave no room for a stalled car. The Brent Spence Bridge and the I-75 approaches are notorious for congestion, and a breakdown there, with narrow shoulders and heavy trucks, is one of the worst places in the region to be stuck.
The region's main airport, Cincinnati/Northern Kentucky International, is actually across the river in Hebron, Kentucky, while Lunken Airport on the east side serves general aviation. Metro buses cover the city, and the Connector streetcar loops through downtown and Over-the-Rhine. The University of Cincinnati, Xavier University and the hospital district in Avondale draw heavy daily traffic.
For a mobile mechanic, Cincinnati's hills shape every visit. Neighborhoods sit on ridges and hillsides connected by winding roads, many houses have steep driveways or no driveway at all, and the older districts have narrow streets with tight parking. The mechanic plans for a level spot, whether that is a garage, the street or a nearby lot.
