Grand Rapids is split by the Grand River, and its main freeways cross right at the heart of downtown. US 131 runs north-south along the west side of the river through the downtown S-curve, connecting Wyoming and Kentwood to the south with Comstock Park and Rockford to the north. I-196, the Gerald R. Ford Freeway, crosses it heading west toward Grandville and Holland and east to meet I-96, which skirts the north and east sides of the city toward Muskegon, Lansing and Detroit. M-6, the Paul B. Henry Freeway, forms a southern beltway across the suburbs between I-196 and I-96, and the East Beltline carries M-44 and M-37 traffic along the eastern edge.
The S-curve and the I-196 and US 131 interchange are the usual trouble spots, especially in a lake-effect squall when traffic slows suddenly and fender-benders back up the ramps. 28th Street is the busiest commercial corridor, and its long string of lots makes it a common place for a car to quit mid-errand. Beyond the core, the city and its suburbs spread out on a grid of wide section-line roads, so reaching a driveway in Alger Heights or a cul-de-sac in Caledonia is usually quick.
Gerald R. Ford International Airport sits southeast of the city in Cascade Township, and its long-term lots are a regular stop for no-starts after a winter trip. The Rapid bus system, including the Silver Line along Division Avenue, serves the core, and many downtown workers park in the city ramps near the arena and the convention center. The ramps by the medical buildings on Michigan Street stay busy all day with staff and patients.
