Harkin identified road development as another measure to increase the profitability of tourism and national parks. His goal was to make the scenery of the Canadian Rockies accessible to automobile traffic through first class motor roads into and through parks. With adequate roads through mountains, there would be increased traffic and significant spending from auto-tourists. The Calgary-Banff Coach Road, completed in 1911, absorbed a significant portion of the Parks budget for years. With no allegiance to the railroad and its dependants, Harkin increased road development and continued to increase accessibility of automobiles into parks. Under Harkin's tenure as commissioner, major roads such as the Banff-Windermere Highway, Edmonton-Jasper-Banff Highway, and the Kicking Horse Trail were built. By 1930, around 400 miles of parks roads were built, with 145 miles servicing the Rocky Mountain Parks.
