The perennial attempt to replicate the success of Sparks St in the desolate and unpopular Byward Market.
The last thing we need to do is to shut down traffic around the market. Parking, sure, but not the traffic. Lots of short stay parking to load the car after shopping. And vehicular traffic means safety for a lot of pedestrians as the eyes on the street are mobile, and anywhere. Makes it a lot less spooky at night. Ask any woman whether they choose to walk down the street most likely to have cars on it at night.
A better solution is woonerfs, traffic calming measures, creating cues that this is a pedestrian realm that cars are allowed to drive through, not roads that the pedestrians should avoid.
