Every option for driving was look at during the EA with the Bathurst Community wanting both direction due to the back up on the Lake Shore. Traffic count had close to 70% of non resident area using QQ as a drive through and away around the Gardiner mess. License Plates were used to determine where drivers live for the % count. There was just over 600 cars using 2 lanes in each direction and that low number allow 2 lanes to be remove since 1,000 was the number for each lane or 2,000 per direction.
Once the portal gets built on the east side of Bay St, you will have the same issue then as it is today at Bay, but will be straight drive, not the current turn unless the clueless driver thinking turning north on Bay will get them downtown.
