Hartford finds another monumental task in its way: a crumbling piece of 20th-century infrastructure, a stretch of the Interstate 84 viaduct adjacent to downtown that is well past its expiration date. Completed in 1965, the elevated thoroughfare was part of the national urban-renewal campaign to ram freeways through downtowns, and it did extraordinary damage to Hartford’s urban fabric. The ideas for what to do with it now range from a plain-vanilla rebuild to a tunnel system more elaborate than Boston’s Big Dig.
