Miami's road system is based along the numerical Miami grid where [[Flagler Street]] forms the east–west [[Baseline (surveying)|baseline]] and [[Miami Avenue]] forms the north–south [[Meridian (geography)|meridian]]. The corner of Flagler Street and Miami Avenue is in the middle of Downtown in front of the Downtown [[Macy's]] (formerly the [[Burdine's]] headquarters). The Miami grid is primarily numerical so that, for example, all street addresses north of Flagler Street and west of Miami Avenue have "NW" in their address. Because its point of origin is in Downtown, which is close to the coast, the "NW" and "SW" quadrants are much larger than the "SE" and "NE" quadrants. Many roads, especially major ones, are also named (e.g., [[Tamiami Trail|Tamiami Trail/SW 8th St]]), although, with exceptions, the number is in more common usage among locals.

With few exceptions, within this grid north–south roads are designated as Courts, Roads, Avenues or Places (often remembered by their acronym), while east–west roads are streets, Terraces, Drives or occasionally Ways. Major roads in each direction are located at one mile intervals. There are 16 [[City block|blocks]] to each mile on north–south avenues, and 10 blocks to each mile on east–west streets. Major north–south avenues generally end in "7" – e.g., 17th, 27th, 37th/Douglas Aves., 57th/Red Rd., 67th/Ludlam, 87th/Galloway, etc., all the way west beyond 177th/Krome Avenue. One prominent exception is 42nd Avenue, LeJeune Road, located at the half-mile point instead.

Major east–west streets to the south of Downtown are multiples of 16, though the beginning point of this system is at SW 8th St, one half-mile south of Flagler ("zeroth") Street. Thus, major streets are at 8th St., 24th St./Coral Way, 40th St./Bird, 56th/Miller, 72nd/ Sunset, 88th/N. Kendall, 104th (originally S. Kendall), 120th/Montgomery, 136th/Howard, 152nd/Coral Reef, 168th/Richmond, 184th/Eureka, 200th/Quail Roost, 216th/Hainlin Mill, 232nd/Silver Palm, 248th/Coconut Palm, etc., well into the 300s. Within the grid, odd-numbered addresses are generally on the north or east side, and even-numbered addresses are on the south or west side.

All streets and avenues in [[Miami-Dade County]] follow the Miami grid, with a few exceptions, most notably in [[Coral Gables, Florida|Coral Gables]], [[Hialeah]], Coconut Grove and [[Miami Beach, Florida|Miami Beach]]. One neighborhood, [[The Roads]], is named as such because its streets run off the Miami grid at a 45-degree angle, and therefore are all named roads.

[[Miami-Dade County]] is served by four Interstate Highways ([[Interstate 75 (Florida)|I-75]], [[Interstate 95 in Florida|I-95]], [[Interstate 195 (Florida)|I-195]], [[Interstate 395 (Florida)|I-395]]) and several U.S. Highways including [[U.S. Route 1 (Florida)|U.S. Route 1]], [[U.S. Route 27 (Florida)|U.S. Route 27]], [[U.S. Route 41 (Florida)|U.S. Route 41]], and [[U.S. Route 441 (Florida)|U.S. Route 441]].

Miami has six major [[causeway]]s that span over Biscayne Bay connecting the western mainland, with the eastern barrier islands along the Atlantic Ocean. The [[Rickenbacker Causeway]] is the southernmost causeway and connects Brickell to [[Virginia Key]] and [[Key Biscayne, Florida|Key Biscayne]]. The [[Venetian Causeway]] and [[MacArthur Causeway]] connect [[Greater Downtown Miami|Downtown]] with [[South Beach]]. The [[Julia Tuttle Causeway]] connects [[Midtown Miami|Midtown]] and [[Miami Beach]]. The [[Florida State Road 934|79th Street Causeway]] connects the [[Upper Eastside, Miami, Florida|Upper East Side]] with [[North Beach (Miami Beach)|North Beach]]. The northernmost causeway, the [[Broad Causeway]], is the smallest of Miami's six causeways and connects [[North Miami, Florida|North Miami]] to [[Bay Harbor Islands]] and [[Bal Harbour, Florida|Bal Harbour]].
