 Some sections were improved to modern highway standards, while others were subsequently bypassed or abandoned.The roads that were not incorporated as highways either became local roads or were consumed by nature.Though many other roads in the province can be considered "colonization roads", such as Yonge Street, Hurontario Street, Provincial Road (later Highway 2), Talbot Trail, and the Penetanguishene Road, they were either constructed for military purposes or by private investment.
