In Ontario, Highway 403 had its shoulders between Hurontario Street and Erin Mills Parkway widened in 2003 so they serve a dual purpose as bus lanes and accident lanes. In the Minneapolis–Saint Paul region of Minnesota, over 270 miles of shoulder have been designated for use by buses. The Route 9 BBS in Central New Jersey which runs along two stretches of shoulders are dedicated for exclusive bus use during peak hours. The bus lanes, which run for approximately 3 miles (4.83 km) are the first component of a planned BBS corridor. In the Chicago area, Pace buses are authorized to use the shoulder of the Jane Addams Memorial Tollway, Edens Expressway, and Stevenson Expressway to avoid traffic congestion.
