Streetcars

Back in the late 1970s, when Washington's Metrorail system first began operating in Arlington County, Virginia, the future of Arlington and other old, inner suburbs was far from certain. Across the Potomac, the District of Columbia was suffering from depopulation, rapidly rising crime rates, and serious fiscal difficulties.

Seattle's South Lake Union Streetcar is a 1.3-mile line that opened in December 2007, the first leg in the city's commitment to new transit and light rail. It passed the half million passenger milestone in its first year, surpassing ridership projections.

 On Tuesday, voters in Portland, Oregon elected Sam Adams as their next mayor. A former Congressional staffer and current Portland city commissioner, Adams -- who is a cyclist -- ran on a platform that emphasized environmental and progressive growth initiatives, including, in the words of the Oregonian, "use [of] the Portland Streetcar and better planning to spur urban renewal." Adams received strong support from the livable streets community, which helped earn him a 52-34 percent margin of victory.
