with a Route 24 continuing north to Madawaska; New York extended the number to New York City in 1924 with its own Route 1. Other states adopted their own systems of numbering; by 1926 all states but Maryland had signed the Atlantic Highway as various routes, usually changing numbers at the state line. In 1925, the Joint Board on Interstate Highways created a preliminary list of interstate routes to be marked by the states, including US 1 along the Atlantic. This highway began at Fort Kent, Maine, and followed the existing Route 24 to Houlton, as well as Route 15 to Bangor, beyond which it generally followed the Atlantic Highway to Miami. In all states but Georgia that had numbered their state highways, Route 1 followed only one or two numbers across the state. The only significant deviation from the Atlantic Highway was between Augusta, Georgia, and Jacksonville, Florida, where Route 1 was assigned to a more inland route, rather than following the Atlantic Highway via Savannah. One of the many changes made to the system before the final numbering was adopted in 1926 involved US 1 in Maine. The 1925 plan had assigned US 1 to the shorter inland route (Route 15) between Houlton and Bangor, while US 2 followed the longer coastal route via Calais. In the system as adopted in 1926, US 2 instead took the inland route, while US 1 followed the coast, absorbing all of the former Route 24 and Route 1 in New England. Many local and regional relocations, often onto parallel superhighways, were made in the early days of US 1; this included the four-lane divided Route 25 in New Jersey, completed in 1932 with the opening of the Pulaski Skyway, and a bypass of Bangor involving the Waldo–Hancock Bridge, opened in 1931. The Overseas Highway from Miami to Key West was completed in 1938 and soon became a southern extension of US 1. With the construction of the Interstate Highway System in and after the 1950s, much of US 1 from Houlton to Miami was bypassed by I-95. Between Houlton and Brunswick, Maine, I-95 took a shorter inland route, much of it paralleling US 2 on the alignment proposed for US 1 in 1925. Between Philadelphia and Baltimore, I-95 leaves US 1 to pass through Wilmington. Most notably, I-95 and US 1 follow different corridors between Petersburg, Virginia, and Jacksonville, Florida; while
