The two are vastly different in terms of use, writer Dan Malouff concluded, but yet are similar in concept. For instance, the High Line was once a freight rail line designed to transport goods to and from the city more efficiently than ground-level rail. Freedom Park, on the other hand, was originally meant to be an elevated highway to help move commuters into the District more efficiently than Wilson Boulevard and N. Lynn Street.

For those who weren’t around in the ’70s, ’80s and early ’90s, the idea of Rosslyn’s “Loop Road Bridge” may seem a bit wacky. N. Lynn Street does get backed up at rush hour, but hardly enough to justify a whimsical, Disney World-esque elevated highway that ran in between skyscrapers and over existing roads, and which did nothing to alleviate traffic on the real bottleneck: the Key Bridge. At the time, however, transportation planners believed that the Loop Road Bridge was “the final piece to a road system that would reduce traffic in the Arlington high-rise district,” as Washington Post reported Charles W. Hall wrote in April 1993.
