As you're out and about (but not while driving!), or if you have a view from above, look for intersections and lanes with intact zones of snow that tires and car heat haven't driven off. Those are "sneckdowns," temporary curb extensions and lane narrowings caused by the snow. They are evidence of surplus lane width, and of other unused or unnecessary area in the roadway.
The zones with snow could become bike lanes, wider sidewalks, pedestrian medians or other road space reallocated for users other than those in cars. They are evidence for ways we have overengineered and overdesigned roadways for car travel and for too-high speeds.
Here are two from December 2016:
|Court and High from Courthouse square - via Twitter|
|South Commercial just north of Madrona - SJ video clip|
The snow lines show why these were not only possible but were good ideas.
Many other streets might be good candidates also, and imagery from snowy periods could be presented to City Council in support of requests for reallocating carspace to support safety and to create more usable space for people walking and biking.
