In 2013, Arlington began installing bike boulevards on the streets a block north and south paralleling Columbia Pike. The bike boulevards offer cyclists an alternative to Columbia Pike itself, which will one day have streetcar tracks.
What’s a bike boulevard?
Bike boulevards are slow-speed neighborhood streets where cars and bikes share lanes, but which are optimized for bikes. They’re quiet local roads, usually lined with single-family houses, where there’s such light car traffic that separated lanes for bikes and cars aren’t necessary.
Bike boulevards are common on the west coast, but as far as I know Arlington’s 9th Street South and 12th Street South bike boulevards are the first in the DC region.
