The World's 18 Strangest Roadways-- Part 4

15. CANTON AVENUE-- Pittsburgh, Pennsylvania. Small cobblestone street in Beechview neighborhood. 37% grade. That's 37 feet up for every 100 feet horizontal. Has an ongoing feud with New Zealand's Baldwin Street which has a 35-38% grade as the world's steepest drivable street. // 16. THE HIGH FIVE INTERCHANGE-- Dallas, Texas. Where I-635 connects to U.S.-75. Tremendous verticle mode here with lanes as high as a 12-story building in places. // 17. LOMBARD STREET-- San Francisco. A curvy icon. Originally had a 27% grade but was too steep for early autos. In 1922, 8 curves added and reduced to 16% grade. It was two-way until 1939. // 18. TIBBITT TO CONTWOYTO WINTER ROAD-- Northwest territory, Canada. Made famous by the History Channel's "Ice Road Truckers." 370 mile ice road from diamond mines over interconnected lakes. //// How Steep Is Too Steep? Wonder How Steep the Turn Off US-12 at Sunset Road in McHenry County Is? --RoadDog
