The Commonwealth Avenue Bridge project continues to snarl traffic coming in and out of the city.
This morning, Acting Highway Administrator Jonathan Gulliver said overall traffic levels are down about 20 percent on the Pike, and he's optimistic about completing the project on time.
Despite the closures and detours, the project has created some unexpected havens. Biking over the BU Bridge has turned from a terror into a pleasure. Commonwealth is suddenly a pedestrian's delight.
And it made us wonder, what if we had these car-free zones in the city every day? What might those look like? And how might they transform both the city's landscape and our relationship with it?
