History
Before 1963, the route did not follow a loop, but ran from Futtsu to Yokosuka to Yokohama. The Yokosuka-Yokohama section was designated as National Highway 45 on 8 July 1887 and became National Highway 31 in 1920 and Route 16 in 1952. On 1 April 1963, Route 16 was extended to Kisarazu, replacing a portion of Route 127 and all of Route 129 when these sections were promoted to Class 1 highways, forming the current route around Tokyo.
