Lewis argues that D.C. needs to look at the success of New York City's High Line park as it tries to repurpose its closed-off trolley tunnels.
"Most cities, including Washington, have defunct infrastructure leftovers. The District recently issued a Request for Proposals to develop new uses for 3,000 linear feet of abandoned trolley car tunnels built in 1948 below Dupont Circle and alongside the Connecticut Avenue NW underpass. Trolley operations ended in 1962, and the tunnels were sealed in 1964.
This is not the first attempt at revitalizing the Dupont Circle trolley tunnel. In 1995-96, the city leased tunnel space to a developer who tried to make a go of an underground food court. It went out of business in a year. With dozens of aboveground cafes and restaurants in the Dupont Circle neighborhood, this was no surprise. Why descend into a sunless tunnel to dine?"
