1) There appears to be overhead tram lines heading along both streets. Following the construction of the MacDonald Bridge trolley lines were extended from Gottingen down North and across the bridge to the Bridge Terminal. This was part of "Route 11" (predecessor to Route 1).
2) I walk this area everyday and the distance to where the bridge starts is the same as Gottingen now. Also the land flattens out so the foot of the bridge is actually not visible from Maynard.
3) Stoplights have only ever been placed at Gottingen and Agricola Street.
No, I think it is North and Gottingen. the second pic showing the traffic problems shows that the current system of lanes was not there in '62 and I think the corner we are talking about is just in "back" of that picture's view.
If you fast forward the video below to about 2:20 you'll see the whole drive down North Street to the bridge:
Neat to see the electric buses going over the Macdonald, and to see there not being a huge empty lot on the Dartmouth side of the bridge (to the left, across Wyse from Dartmouth Shopping Centre). I knew there were buildings there before, but there were some large ones.
