Louisville, Kentucky has asked its residents for help in determining the future vision for the city, and citizens sent in thousands of ideas on how to improve Possibility City. Among the crowd-sourced suggestions were many promoting alternative transportation, whether improving bike infrastructure to building light rail to, well, even more alternative methods of getting around. Local Russ Renbarger proposed what he calls RiverZips, a mile-long zip line across the Ohio River that would convey people between Kentucky and Indiana—more of a ride than an adventure, says Insider Louisville. Renbarger is founder of digital marketing firm Red Tag Ideas, based in the city’s suburban East End. It sounds far-fetched, but a recent municipal push to liven up Louisville could be just what his idea needs. The plan calls for attaching the zip line high atop a railroad-bridge-turned-pedestrian-bridge that connects downtown Jeffersonville, Indiana with Louisville's Hargreaves-designed Waterfront Park. Riders would land in a staging area in the park near the base of the Big Four Bridge. Mayor Greg Fischer called ziplines “far-out” while he unveiled citizens’ ideas for the Vision Louisville project, in comparison to more practical plans to revitalize the city, like more bike lanes. There are some logistical difficulties to the RiverZips proposal: the heads of the Louisville Waterfront Development Corporation worried it would sit idle in the winter, and perhaps be “too obtrusive” at other times. Renbarger said the launch platforms could be removed, if necessary, and that a nearby iceskating rink could use the site’s base for vending during the winter. A former member of the Army Corps of Engineers, Renbarger says the 1-mile zipline is plausible. For now, though, the idea remains unfunded. But Renbarger, a “man about town” who appeared on the reality TV show "Southern Belles: Louisville," has people talking.
