Ralph Buehler and John Stowe wrote a chapter on bicycling in the recent book Capital Dilemma: Growth and Inequality in Washington, DC. The chapter covers the history of bicycle planning and policy in Washington from 1970 to the present.
It focuses on the time period since the late 1990s when the District of Columbia’s population and economy increased strongly. Bicycle planning in the region has its roots in the 1970s, but experienced a hiatus in the 1990s, and has witnessed a ‘renaissance’ since the late 1990s. In the 1970s and 1980s, local jurisdictions focused their bicycle policies on the provision of off-street paths—often shared with pedestrians. Since the late 1990s, all jurisdictions have greatly expanded their on-street bicycle lanes and implemented other innovative programs. Washington, DC, Alexandria City, and Arlington County have implemented more bike-friendly policies and have been at the forefront of experimenting with innovative measures. In spite of the progress, many challenges for cycling remain. Area cyclists are predominantly male, between 25 and 65 years old, White, and from higher income groups. Cycling appears to be spatially concentrated in neighborhoods of the urban core jurisdictions that experienced strong population growth. Moreover, the network of bicycle paths and lanes is still fragmented and often requires cyclists to mix with heavy or fast moving car traffic.

Also, today is the 11th Anniversary of the Washcycle. Back then WABA was moving offices, NPS was studying a proposal to extend the Mount Vernon Trail to the American Legion Bridge and I was complaining about how it had been 6 years since the ribbon cutting ceremony for the Met Branch Trail, but it still wasn't finished. Luckily that's not an issue anymore.
