Arlington County is installing a traffic signal at Wilson Blvd & N Livingston St, to replace an aging mid-block crossing designed to improve accessibility to Powhatan Springs Skate Park. The improvements look good, and will improve north-south connectivity in this area which has few safe crossings over Wilson Boulevard, but the project fails to make appropriate improvements to the bike lane.  Per the NACTO Guidance enshrined in the County's Bicycle Element of the Master Transportation Plan, the bike lanes on Wilson Boulevard should be PROTECTED, not just buffered, due to the large number of vehicles that travel on Wilson. This omission is likely due to inflexibility from the Fire Marshal, despite explicit authority granted in the Virginia Fire Code that would allow flexibility in these situations to meet the public safety goals of the jurisdiction (such as Vision Zero!).
