Kevin Dumler posted this to Twitter, and it caused me to pay more attention to all the utility and construction projects going on in the central city that have reduced general purpose travel lanes (car lanes). What follows are some photos of other locations.
It is only in this last example, on J Street between 12th and 10th, where there was some congestion. However, no vehicles were being stuck at signals, nor failing to make it through the signal at 11th Street, so this is very minor congestion.
The point, well made by Kevin, is that we have excess capacity for motor vehicles on many of our roadways, particularly three lane roadways, that could better be used for other things, like bike facilities, wider sidewalks, planter strips or wider planter strips. Or even narrowing the street for housing!
