Kansas City spreads across both banks of the Missouri River, and its interstates knot together in a tight downtown loop before fanning out in every direction. I-70 runs east toward Independence and St. Louis and west into Kansas toward Topeka. I-35 cuts diagonally from the Northland through downtown and southwest into Johnson County. I-29 heads north past the airport toward St. Joseph, and I-435 forms an enormous outer loop around both the Missouri and Kansas sides. I-470 links the southeast suburbs around Lee's Summit, and US 71, Bruce R. Watkins Drive, carries traffic from downtown south toward Grandview and I-49.
The downtown loop, where I-70, I-35 and I-670 tangle together, is the usual trouble spot, along with the river crossings into the Northland and the I-435 interchanges at rush hour. The metro is spread out, so commutes are long and fast, and a breakdown on a highway shoulder at speed is genuinely dangerous. Surface streets mix a regular grid in Midtown with curving boulevards and parkways through the older neighborhoods, which keeps most homes easy for a mechanic to reach.
Kansas City International Airport sits far north in Platte County, and its parking lots are a common place for a car to refuse to start after a trip. The streetcar runs along Main Street from the River Market through downtown and the Crossroads, and buses cover the main corridors, though most households here drive nearly everywhere.
Because the metro straddles the state line, plenty of people live on one side and work on the other. State Line Road divides the two, and a car that quits near the border is just as reachable as one in the middle of either side.
