The highway's southern terminus is at Punta Gorda, Florida, at an intersection with US 41. Traveling north, US 17 joins up with US 50 in Paris, Virginia, and the northern terminus of US 17 is in downtown Winchester. This is also the point at which the portion of US 50 called the Northwestern Turnpike begins.
Though US 1 is generally considered to be the highway that runs alongside Interstate 95 (I-95), US 17 runs parallel to I-95 for much of its extent and even shares the same physical road for short spans in Fredericksburg, Virginia, and Ridgeland, South Carolina. As such, US 17 is out of sequence in the U.S. Highway numbering plan (US 17 would, under the plan, run parallel to and between US 15 and US 19; the U.S. Highway following that path is instead marked US 219).
US 17 begins in downtown Punta Gorda at US 41 (Cross Street), just to the west of the Tamiami Trail. After running east, it runs roughly north along the Peace River, through Arcadia, Zolfo Springs (where it crosses the Peace River), and Wauchula. At Fort Meade, it joins with US 98, which follows it northward (westward on US 98) until Bartow. While US 98 goes northwest, US 17 goes northeast.
US 17 begins a long concurrency with US 92 just north of Winter Haven in Lake Alfred (US 92 following eastbound), which takes both highways through Kissimmee, where they join US 192. Like US 92, US 17 roughly parallels I-4 along the overlap. When all three meet US 441, US 192 follows US 441 southbound, while US 17/US 92 follows US 441 north into downtown Orlando. US 17/US 92 then splits from US 441 at State Road 50 (SR 50, Colonial Drive) and jogs east, splitting back north from SR 50 when it meets SR 15 (Mills Avenue).
US 92 then splits away from US 17 north of DeLand, as US 92 continues east to Daytona Beach on International Speedway Boulevard, while US 17 continues north toward Palatka, where it again crosses the St. Johns River.
In Clay County, US 17 runs through suburban Jacksonville. The northern stretch of US 17 in Clay County is known as Park Avenue.
In Jacksonville, the southern portion of US 17 is known as Roosevelt Boulevard. Here, the highway goes past Naval Air Station Jacksonville (NAS Jax). Near downtown Jacksonville, US 17 joins I-10 for approximately one mile (1.6 km), before merging into I-95. US 17 then exits onto Union Street and continues as North Main Street until the Nassau County border. It then continues until it reaches the Georgia state line, crossing over the St. Marys River.
US 17 enters South Carolina in Jasper County as a two-lane road and within eight miles (13 km) enters Hardeeville, where it becomes a four-lane configuration. US 17 intersects I-95 in Hardeeville and runs parallel to I-95 until Ridgeland, where it merges with the Interstate until Point South. At Point South, US 17 leaves I-95 and heads eastward into northern Beaufort County, sharing a concurrency with US 21 until Gardens Corner. US 21 splits off to Beaufort while US 17 heads northeast into the ACE Basin and Colleton County. This stretch of road has been upgraded from a two-lane to a four-lane configuration, due to safety concerns.
Once in Jacksonboro, the road enters Charleston County, crossing the Edisto River and maintains a four-lane configuration for the remainder of the state. The road passes through several rural communities as it approaches Charleston from the west. In Charleston, the 3.6-mile (5.8 km) section running from South Carolina Highway 171 (SC 171) to Sam Rittenberg Boulevard has been named the "Charleston Nine Memorial Highway", in honor of nine Charleston firefighters killed in the line of duty in the Charleston Sofa Super Store fire on June 18, 2007.[1] US 17 passes through the West Ashley community before it traverses the Ashley River Drawbridges to the Charleston Peninsula. From the drawbridges, it is known as the Septima Clark Crosstown Connector and is mostly routed north of the affluent historical areas of the city. Upon reaching the I-26 terminus, US 17 becomes limited-access and above grade as it approaches the Cooper River via the Arthur Ravenel Jr. Bridge. The stretch of US 17 in Charleston is infamous among locals for its traffic congestion, especially on weekday mornings.[citation needed]
From 1956 until 1993, US 17 signs in Florida featured black numbering on a yellow shield. The color coding of U.S. Highways by the Florida Department of Transportation was stopped when the state could only use federal funding for stock black-and-white; a few yellow US 17 signs remain.[citation needed]
South Carolina
US 17 has had slight variations over its history in South Carolina. US 17 once traversed the Cooper River on the John P. Grace and Silas N. Pearman memorial bridges before the Arthur Ravenel Jr. Bridge replaced both in 2005.[4] US 17 also ran through downtown Myrtle Beach before the new bypass route was finished in order to alleviate heavy traffic. US 17 Alternate was commissioned as a route between Point South and Georgetown, mostly for trucks who wished to bypass Charleston and the weight restrictions of the former bridges.
Hurricane Charley Highway
On August 13, 2004, Hurricane Charley made landfall near the southern terminus of US 17 at Punta Gorda.[5] The hurricane threatened to hit much of the highway,[6] affecting the route in Florida from Punta Gorda to north of Orlando (when Charley followed the route of I-4 out to sea). The Georgia stretch of US 17 was not hit but was under a hurricane warning. When Charley made landfall again in South Carolina, its trail through Virginia was close to US 17.[citation needed]
