Yonge Street
Provincial downloading separated Yonge Street from Highway 11 during the 1990s. As a result, Highway 11 does not start until Crown Hill just outside Barrie, several kilometres north of where the name "Yonge Street" ends. The Guinness Book of World Records no longer lists Yonge Street as the longest street in the world and has not chosen a replacement street, but cites the Pan-American Highway as the world's longest "motorable road".
Delaware State Route System
In 1934, the entire length of US 13 between Dover and Wilmington was widened into a divided highway, which at the time was the best superhighway and the longest stretch of divided highway in the world. During the course of the 1930s, several other state roads were constructed while others were widened into divided highways. In 1935, the DSHD took over maintenance of all remaining county roads, tripling the mileage of the state highway system, and took over several city streets in Wilmington in 1936. Progress on improving the state highway system slowed during World War II; the only major project completed during that time was the construction of the high-level St. Georges Bridge to replace a lift bridge destroyed by a ship in 1939. Following the war, several highway improvement projects took place including widening more roads to divided highways. On August 16, 1951, the Delaware Memorial Bridge and its approach road opened to traffic, providing a fixed road link for US 40 across the Delaware River to New Jersey and replacing ferry service that previously existed. Following the completion of the bridge, traffic along US 13 and US 40 increased, with plans made for a new freeway to handle the increased traffic. In 1957, US 13 was widened into a divided highway between Greenwood and Harrington, providing a divided highway running the north-south length of the state.
