U.S. Route 101
U.S. Route 101, or U.S. Highway 101 (US 101) is a north–south United States Numbered Highway that runs through the states of California, Oregon, and Washington, on the West Coast of the United States. It is also known as (The Royal Road) where its route along the southern and central California coast approximates the old trail which linked the Spanish missions, pueblos, and presidios. It merges at some points with California State Route 1 (SR 1).
Connecticut Route 101
In 1932, Route 101 was extended westward across the entire state. It now began in Canaan and ran through Hartford to Phoenixville, where it continued east along its 1920s alignment. The portion of old Route 101 between South Chaplin and Phoenixville became part of Route 91 (now Route 198). Old state highways 137 and 139 were combined into a new Route 202. In 1935, U.S. Route 44 and U.S. Route 202 were designated by AASHO. US 44 used the alignment of the extended Route 101. Old Route 202 was renumbered to Route 101 (since the number was now available) to avoid a numbering conflict with US 202. This route number change was done in cooperation with Rhode Island, which designated the continuation as Rhode Island Route 101. Route 101 was one of the few state routes that survived the 1932 state highway renumbering.
