Snake Alley in Burlington, Iowa

Built in 1894 and completed in 1898, Snake Alley in Burlington, Iowa was originally devised by three German immigrants who wanted a faster link between Heritage Hill and Burlington's downtown business district. Because of the steep grade, the road was made to wind down the hill with bricks laid at an angle so horses had better footing as they descended. San Francisco's iconic Lombard Street has a few more turns in it, but Ripley's Believe It, Or Not! once recognized Snake Alley as the 'Crookedest Street in the World'.
