Majority of the main routes are urban "county" roads funded by York Region. Each one of them is assigned with a number, each shown by a shield shaping like a flowerpot. York Regional Roads, like roads in Toronto, are laid out in a grid-like system. Most of the north-south routes inherit names from Toronto. For example, Warden Avenue in Toronto is still called Warden Avenue in Markham. Several of the east-west York Regional Roads in Markham still retain their historical concession road numbers (as opposed with the concession roads in Toronto which have all been named), such as 14th Avenue and 16th Avenue (they are the 14th and 16th main routes from Front Street in Toronto). The York Regional Roads are laid out in a grid pattern about 2 kilometers apart. The regional road system is particularly successful due to the landscape across Markham and York Region is relatively flat.
