Harrisburg sits on the east bank of the Susquehanna River, and its highways wrap around the city and cross the river into the West Shore. I-81 runs along the north side toward Carlisle and Hazleton, I-83 runs along the east side as the Capital Beltway and crosses the river into Camp Hill and New Cumberland, and the Pennsylvania Turnpike crosses the southern edge. I-283 links I-83 with the Turnpike and the airport, and US 22/322 runs north along the river toward State College and east toward Hershey. The river is wide here and dotted with islands, which is why the bridges are so long.
Front Street follows the river along downtown and Midtown, and Second Street and Cameron Street carry traffic north and south through the city. The I-81 and I-83 interchange and the bridges over the Susquehanna back up at rush hour, and a breakdown on the John Harris Bridge or in the I-83 merges near the city stops traffic quickly. Older bridges, including the Market Street Bridge and the Harvey Taylor Bridge, link downtown with the West Shore.
Harrisburg International Airport sits south of the city in Middletown, and Amtrak's Keystone service runs from the downtown station to Philadelphia. Capital Area Transit buses serve the city, and Penn State Harrisburg, Harrisburg University and HACC draw daily traffic. The State Capitol complex and the state office buildings bring a large workforce downtown every weekday, and the Farm Show Complex north of Midtown hosts big events through the year.
For a mobile mechanic, Harrisburg is a mix of rowhouses and driveways. Downtown, Midtown and Uptown have rowhouses with street parking and alleys, Allison Hill has steep streets, and the suburbs have driveways and garages. State office lots and garages are workable when the property allows outside service, and the West Shore suburbs across the river are newer and roomier, with driveways that suit longer jobs.
