Niot a bad idea but the streetcar track lanes would need to be open and drivers would simply drive on them.Back on to street design, I’d like to see certain blocks closed to traffic entirely or at least converted into woonerfs. University to John is one of those ideal blocks. There are no parking garage entrances or building driveways and there are alleyways behind businesses for commercial deliveries. Most of this block is a public square. There would still be Mirvish Way for tour bus and taxis for passenger drop offs and parking.
Spadina to Portland is another such block. By closing off a block like these, there’d be no way for drivers to use King for crosstown access, even if they disobey rules. Their path would be physically blocked and that would put an end to a lot of the law breakers. What’s the point of driving on to King if there’s physically no road every few blocks?
