Saturday, the Metro system will grow in length by 10% with the Silver Line, first envisioned in the mid-1960s. A lot has changed from the original plans for Metro. Today, DDOT circulated a 1968 map of the planned system.
In the wake of the 1968 riots, DC pushed WMATA to reroute what’s now the Green Line through some of the harder-hit neighborhoods. In 1970, the WMATA Board voted to change the “E route” from Massachusetts Avenue and 13th Street and instead run it along 7th Street to Shaw and then 14th Street to Columbia Heights.
The 1970 decision also deleted the “Petworth” station, which would have been at Kansas Avenue and Sherman Circle. The “Georgia Avenue” station would have been under Kansas Avenue at Georgia and Upshur, in the heart of Petworth, but the alignment later shifted south to New Hampshire Avenue.
In addition to the many station name changes (you won’t see Ardmore, Voice of America, or Marine Barracks stations on the map today), there have been a few pretty significant changes to alignments and station locations.
At the time of this map, the line we know today as the Blue Line had a split terminus, with some trains running to Franconia and some trains running to Backlick Road (and a potential future extension to Burke).
In the northwestern part of the region, the Red Line was to stop at Rockville, instead of running all the way to Shady Grove. The northern Green Line was also shorter, including a station between Berwyn Road and Greenbelt Road, instead of further north at I-495, where the current Greenbelt station is.
Along the Orange and Blue lines, there were to be two more common stations, one at Oklahoma Avenue and one at Kenilworth Avenue (River Terrace) before the lines split. The Minnesota Avenue station was not in the plan at the time.
The southern Green Line was the subject of lots of controversy between 1968 and its completion in 2001. There were two competing routes planned, one to Branch Avenue and an alternate route to Rosecroft Raceway. The 1968 map here shows the line going to Branch Avenue via Alabama Avenue.
But later, WMATA settled on using the Rosecroft alignment in DC, via Congress Heights, and the Branch Avenue alignment in Prince George’s County. This created in the “jog” along the District line where the Southern Avenue station is located.
The map also shows potential future extensions in blue. Today’s Silver Line is included, though it stays in the median of the Dulles Access Road instead of detouring through Tysons Corner (which was much smaller then; the mall first opened in 1968). Also shown are lines along Columbia Pike in Virginia and extensions to Bowie, Brandywine, Gaithersburg, and Laurel. The extension to Largo was actually built and opened in 2004.
