The Keys , this sign is a tourist attraction US 1 officially begins its northward journey at the
Monroe County courthouse at the intersection of Whitehead and Fleming streets in
Key West. It proceeds south as Whitehead Street, a two-lane street, until the intersection with Truman Avenue, which takes it east through central Key West. Truman Avenue becomes North Roosevelt Boulevard about east and remains so until leaving the island; US 1 expands to four lanes along its length. The road follows the northern shore of this section of Key West, then after curving southward, it meets
SR A1A head-on at a
T intersection before continuing east. This intersection also marks the southern terminus of the
Overseas Highway, which US 1 is known by between here and mainland Florida. past
Naval Air Station Key West, and
Rockland Key, where the Overseas Highway drops down to a two-lane road. It then crosses
East Rockland Key,
Big Coppitt Key (and its
congruous district),
Saddlebunch Keys,
Sugarloaf Key,
Park Key,
Cudjoe Key (and its
congruous district),
Summerland Key,
Ramrod Key,
Middle Torch Key,
Little Torch Key,
Big Pine Key (and its
congruous district),
Scout Key, and
Spanish Harbor Key. The highway expands to four lanes as it crosses the
Bahia Honda Bridge, then reduces to two lanes as it traverses
Bahia Honda Key,
Ohio Key,
Missouri Key, and
Little Duck Key. After Little Duck Key, US 1 enters
Knights Key,
Boot Key,
Key Vaca, and the town of
Marathon via the
Seven Mile Bridge, thus leaving the lower Keys. US 1 runs through Marathon as a four-lane road. After Key Vaca, the road becomes two-lane once more and runs through
Fat Deer Key, where it forms the northern boundary of the city of
Key Colony Beach. It then continues wholly in Marathon through
Long Point Key,
Crawl Key, and
Grassy Key. The road then crosses to
Little Conch Key and then
Conch Key, both part of the
Duck Key district. US 1 then crosses to and traverses
Long Key, which is mostly unincorporated except for the city of
Layton, which the highway passes through. The road then reaches
Craig Key, and then the village of
Islamorada including
Lower Matecumbe Key,
Tea Table Key,
Upper Matecumbe Key, and
Windley Key. US 1 crosses a drawbridge onto
Plantation Key, where it expands to four lanes and then leaves Islamorada as it crosses to
Key Largo. Immediately the Overseas Highway enters
Tavernier, where it temporarily splits into a
pair of one-way roads through the
community. Soon, the road enters the
community of Key Largo, At the northern end of the Key Largo district, about two-thirds of the way along the island, US 1 intersects
County Road 905 (CR 905), which offers an alternative route out of the Keys via
North Key Largo and the
Card Sound Bridge. Signage approaching the intersection directs northbound motorists to take this alternative route if the lights on it are flashing. US 1 swings to the northwest, forms the southern boundary of North Key Largo, and becomes a two-lane divided road after the intersection. After crossing the
Jewfish Creek Bridge (where it enters unincorporated Monroe County again) and traveling along Cross Key, US 1 crosses Manatee Creek, along with the
Miami-Dade County boundary, and reaches the mainland, marking the northern end of the Overseas Highway.
Miami-Dade County on Biscayne Boulevard; US 1 can be seen on the right side of the picture. For the first in
Miami-Dade County, US 1 is a divided two-lane road bordering
Everglades National Park on the west. It is named South Dixie Highway from the county line to
Miami. Its first major intersection is with the north end of Card Sound Road south of
Florida City. Similarly, to the south, signage directs southbound travelers approaching this intersection to take Card Sound Road if the lights on it are flashing rather than taking US 1 south to
Key Largo. Just north of the Card Sound Road intersection, US 1 meets the southern end of
Krome Avenue (
former SR 997) and then enters Florida City. Here, US 1 intersects
SR 9336, providing access westward to Everglades National Park; at the same intersection, Palm Drive (former
SR 906) likewise provides access eastward to
Biscayne National Park. From here northbound, the South Dixie Highway is paralleled by the
South Dade TransitWay along the former
Florida East Coast Railway alignment. Near-immediately northbound of the Palm Drive intersection, US 1 meets the southern end of the
Homestead Extension of Florida's Turnpike and then crosses into
Homestead at South 328th Street. The road then curves northeast through Homestead, parallel to
Florida's Turnpike, leaving the city north of South 304th Street and continuing northeast through the communities of
Leisure City,
Modello,
Naranja,
Princeton, and
Goulds. At West 112th Avenue/
Allapattah Road (
SR 989), US 1 enters the incorporated town of
Cutler Bay, soon passes under the Homestead Extension of Florida's Turnpike, and continues northeast in the town until at South 186th Street it forms the town's border for two blocks before leaving at South 184th Street. From here, the road continues northeast from this point, forming the western boundary of
Palmetto Bay. In
Perrine, it meets
SR 994, and then divides into a one-way pair of streets, with northbound traffic directed east one block of the southbound traffic along a sweeping curve between South 183rd and South 168th streets. After the two directions of traffic rejoin, the road meets
Coral Reef Drive (
SR 992), then passes through Rockdale and Howard until it reaches South 136th Street (Howard Drive), meets the southern terminus of
SR 973 a block later, and serves to divide
Pinecrest to the southeast and
Kendall and
Dadeland to the northwest for the next few miles. The road is also known as Pinecrest Parkway through this section. Also through this section, US 1 meets the eastern terminus of
SR 990, the southern terminus of the
Palmetto Expressway (
SR 826), and the eastern terminus of
SR 94 at
Kendall Drive.
Dadeland South station lies just north of the Palmetto Expressway, on US 1's western side, and acts as the handover point between the South Dade TransitWay and the
Metrorail line, which proceeds to parallel US 1 for most of its subsequent journey into
Downtown Miami. North of
Snapper Creek (Canal C-2), US 1 continues northeast and enters another section of unincorporated Miami-Dade County. Here, US 1 forms the
Snapper Creek Expressway (
SR 878)'s eastern terminus. The South Dixie Highway then crosses into
South Miami at South 80th Street. At
SR 959 (
Red Road/West 57th Avenue), US 1 leaves South Miami and enters
Coral Gables, passing the main campus of the
University of Miami and headed northeast. At West 38th Avenue (Brooker Street), it leaves Coral Gables and enters Miami, heading northeast toward the southern terminus of
I-95 just south of Downtown Miami. At this point, there is a signage gap in the route, though since 2013, it is federally and state defined as cosigning with I-95 and
SR 970 all the way to Biscayne Boulevard, where US 1 signage resumes. However, some mapmakers like
Rand McNally and
Google Maps continue to sign US 1 along its original alignment via
Brickell Avenue. In Miami, US 1 first intersects
SR 976, followed by the south end of
SR 9, which ends up running concurrent with I-95 and is also I-95's state designation through most of Florida. About east, it meets the national southern terminus of I-95, which it joins over the
Miami River into downtown. The road is then named Biscayne Boulevard through the rest of Miami-Dade County as it proceeds north on
Biscayne Bay. As Biscayne Boulevard, US 1 becomes a one-way pair at an intersection with SR 970. Two blocks north, it reaches
SR 968 (Flagler Street), the north–south baseline for most of Miami-Dade County. US 1 then passes by the western end of
Bayfront Park and then intersects Port Boulevard (Northeast 6th Street), providing access to
PortMiami, with
Kaseya Center at the northeastern end of the intersection. For the next few blocks, it passes by
Museum Park, with
I-395 at the northern end, which also marks the national southern terminus of
US 41. US 1 continues through
Midtown Miami, intersecting with the national southern terminus of
US 27 one block south of
I-195 next to the Julia Tuttle Causeway. North of I-195, the road continues through Miami as a residential road, intersecting
SR 944,
SR 934, and
SR 915 before leaving Miami. Moving further inland, the boulevard replaces East Sixth Avenue at 61st Street. It enters the village of
Miami Shores at North 87th Street. Crossing the Biscayne Canal, Miami Shores becomes
North Miami. In North Miami, it intersects
SR 922, leading to the Broad Causeway and
SR 916. In
North Miami Beach, it intersects
SR 826 and
SR 860. The road enters
Aventura at
Greynolds Park. It continues north-northeast through the city of Aventura, curving due north at North 187th Street and northeast at North 203rd Street. In Aventura, it intersects
SR 856 at the southwest of
Aventura Mall, and, after intersecting the former
SR 854, it leaves Miami-Dade County.

Port St. Lucie Boulevard (PSL Boulevard;
SR 716). Further north, Crosstown Parkway (westbound) and Village Green Drive (eastbound) intersect with US 1 approximately halfway between Prima Vista Boulevard and PSL Boulevard; along with Prima Vista Boulevard, Crosstown Parkway provides Port St. Lucie with a much needed second, higher-capacity direct connection between US 1 and
I-95. Continuing north into
White City it intersects
CR 712 (Midway Road). In
Fort Pierce, it meets the eastern terminus of
SR 70 and, a few miles to the north,
