20th Avenue NW: before and after
On their blog, the Seattle Department of Transportation highlights the recently finished changes to 20th Avenue NW.
This summer, SDOT added bike lanes on either side of the road to help both bicycles and cars.
"The recent changes on 20th Avenue NW demonstrate how SDOT is better supporting cycling while still addressing the needs of drivers," according to SDOT. "As part of Bike Master Plan implementation, we removed the center turn lane to install bike lanes while also preserving on-street parking. These bike facilities run for a half mile in both directions on 20th Avenue NW from Market Street to NW 65th Street."
SDOT took this approach to 20th Avenue NW because of its low volume of traffic and small number of turning movements, providing an opportunity to improve bicycle access along the street without affecting vehicular traffic flow, inhibiting access to residential side streets or removing parking.
