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".
Ryfast
When the last section was drilled on 26 October 2017, Ryfast became the longest undersea road tunnel in the world, with its 14.3km length greater than the Tokyo Bay Tunnel in Japan (9583m.) and the Shanghai Yangtze River Tunnel (8950m.) in China.
