” The answer to one of today’s most difficult urban planning problems may lie in the Middle Ages. In cities and towns across America, freeways cut through communities, creating urban dead zones that sever neighborhoods from each other. To heal that damage, the city of Columbus, Ohio built a type of urbanized bridge that was common in Europe between the 12th and 17th centuries.
In Medieval and Renaissance Europe, imaginative, multifunctional bridges known as “habitable bridges” were quite common. Some hosted markets. Others contained mills that harnessed the power of the river. Many housed defensive towers or featured chapels. Beyond the novelty of having buildings on a bridge, they were highly functional, as they became natural venues for commercial trade… By the 18th and 19th centuries, the construction of habitable bridges was phased out in Europe as the disciplines of architecture and engineering became divorced…
That brings us back to Columbus. In the late 1960s, a major highway (now Interstate 670) was built through town, carving a 200-foot-wide gash in the city that separated downtown Columbus from the nearby Short North neighborhood. A plan for capping the highway was developed in 1996, and finally completed in 2004. Technically, the project consists of three connected bridges: Car traffic passes on the middle span, flanked on either side by platforms that support storefronts and sidewalks. The three bridges fit together into one urbanized overpass that’s home to a handful of restaurants and shops, all of which turn their backs on the highway. “I think the success of it is that most people don’t even know they’re on a bridge,” says architect David Meleca, who designed the retail portion of the project…
Meleca acknowledges that a bridge like his might not work for every highway crossing, but on High Street, renting the space hasn’t been a problem so far. “It’s added a really strong connection with the downtown,” says Meleca. “Before the bridge was done, you would’ve never walked across that freeway. It was a typical utilitarian, scary freeway crossing.” Extending the urban streetscape across the highway shields pedestrians from the roar of the road below and lifts a psychological barrier between neighborhoods, healing a generation-old wound created by the Interstate Highway System.”
