Navigating the RiNo Art District, whether by walking, rolling or driving, can be a headache. But one aspect of local travel has gotten considerably easier since summer, despite ongoing construction in the popular neighborhood. The new 35th/36th Avenue Bridge has made traversing the railroad tracks that bisect RiNo a breeze. Where once you had to divert for blocks to find a place to cross the multiple railroad tracks to get to, say, Wazee Street from Blake Street, now it’s simply up and over. The bridge was a long time coming — and the $6.7 million price tag wasn’t the biggest issue.
