Bringing this thread back from oblivion because it seems more appropriate for this than the Alexandria Bridge Replacement thread.
I put out a brief idea about getting traffic out of the By Ward Market and, particularly, off King Edward Avenue.
Here is a slightly more detailed image of that idea:
It requires about 700 metres of new 4-lane roadway, plus connections and MUPs. The majority of which can be built without disturbing current traffic patterns. All of the new roadway can be at grade, or slightly above grade so that pedestrian underpasses can be added. In the diagram, I have kept the Macdonald-Cartier Bridge’s ‘tail’ elevated for a bit, so that it doesn’t become a roller-coaster. After passing over the MUP ‘culvert’, it drops to grade so that it can intersect with St. Patrick. There is no need to tunnel anything. Just make it relatively easy for active transportation to cross it. I have a crosswalk where it meets St. Patrick, a MUP ‘culvert’ near the middle, and the Union Lay-up at the other end. The greenspace on both sides of the roadway should be usable.
The idea makes use of the existing ‘Union Lay-up’ (which the STO currently uses for their buses) as the extension of a narrowed King Edward. I have placed a second roundabout on King Edward, south of the underpass, so that the ramps can be used for either north-bound or south-bound traffic. This also frees up a bunch of parkland.
Forsey Street disappears, and Bruyere Street gets cut off by the new road. I have moved the tennis courts to the Bruyere-side of the big road, so they are not lost. I have added a parking lot for those tennis courts – but that would not be a necessity.
De La Salle HS gets additional buffer space out front, and the Chinese Embassy gets a better entrance, from an intersection.
I have removed the rest of the roundabouts south, along King Edward. They were an unnecessary expense at this point.
Something to remember: Since the future Alexandra Bridge SHOULD NOT HAVE CAR TRAFFIC, St. Patrick will probably be much less busy, without the cut-through traffic, heading to/from the bridge.
