Detroit-Superior Bridge underpass closer to "Low Line" vision with federal grant

State of play: The U.S. Department of Transportation awarded Cuyahoga County $7 million from its new Reconnecting Communities and Neighborhoods grant program to reimagine the underside of the historic bridge, where streetcars operated from 1918 to 1954.

Zoom in: The DOT funding encompasses both a feasibility study and an engineering plan, but not actual construction.

Catch up quick: Cuyahoga County Executive Chris Ronayne has been trumpeting the potential of the bridge since he took office last year, floating the idea of the "Low Line" — Cleveland's answer to New York's "High Line. "

Flashback: When the Detroit-Superior Bridge opened in 1918, it was the world's largest double-deck concrete structure.

• The 3,100-foot-long bridge was Cleveland's first fixed, high-level bridge and, by 1930, the nation's busiest.
