High Quality Content by WIKIPEDIA articles! King`s Highway 9, also known as Highway 9, is a provincially maintained highway in the Canadian province of Ontario. Often cited as an example of poor planning, Highway 9 has been divided into two segments since January 1, 1998, when the segment between Harriston and Orangeville was downloaded to the various counties in which it resided. The western segment of the highway begins at Highway 21 in Kincardine, near the shores of Lake Huron. It travels 73 km (45 mi) to the junction of Highway 23 and Highway 89 in Harriston. The central segment is now known as Wellington County Road 109 and Dufferin County Road 109. At Highway 10 in Orangeville, Highway 9 resumes and travels east to Highway 400. The highway once continued east to Yonge Street in Newmarket, but is now known as York Regional Road 31.
