Route History for US 1 in Rhode Island

• In 1926, US 1 was marked as NE 1. The road was paved, and followed nearly the same route it does today. Places where NE 1 veered from US 1's current path are in Wakefield and near Charlestown. In Wakefield, NE 1 followed Old Tower Hill Road, Main Street, and Post Road. Between Perryville and Charlestown, NE 1 followed Post Road and Old Post Road.
• By 1928, NE 1 had been renumbered as US 1.
• By 1950, US 1 had been realigned between Wickford and Narragansett. During this time, US 1 followed the path of what is now RI 1A.
• By 1963, US 1 had been realigned to its original (and current) path. Part of the road had been widened to 4 lanes around Wakefield and Perryville.
• By 1969, US 1 had been widened to 4 lanes from Allenton to Westerly. North of Allenton, I 95 had been completed in the Providence area, replacing US 1 as a major through route from the Massachusetts state line to East Greenwich. There have been no major changes to US 1 since 1969.
