U.S. Route 23 marker

U.S. Route 23 (US 23) is a long north–south U.S. Highway between Jacksonville, Florida, and Mackinaw City, Michigan. It is an original 1926 route which originally reached only as far south as Portsmouth, Ohio, and has since been extended.

U.S. Route 23 begins at U.S. Route 1 (Ocean Street) at the northern end of downtown Jacksonville, starting as a one way pair, with the northbound lanes meeting with Florida State College. It is also unsigned State Road 139 from its southern terminus to its interchange with US 1 in northwestern Jacksonville (SR 139 continues east along SR 10A from the end of US 23 to SR 115). West of I-95, US 23 ends the one way pair, continuing as Kings Road through northwestern Jacksonville, as an off grid road. A few miles to the west, US 23 meets with US 1/SR 15 (Martin Luther King Jr. Parkway), becoming concurrent with the highway through the rest of its journey through Florida. The road continues northwest, intersecting with Interstate 295 and eventually makes its way out of Jacksonville. At Callahan, US 1/US 23 meets with U.S. Route 301, beginning a three way concurrency as the road continues northward towards the St. Mary's River, leaving Florida and entering Georgia.
