"I would favour extending the Spadina ROW further north, or creating a streetcar ROW on Church or Bathurst."
--------------------------------------
Neither is nearly wide enough to accomodate one, unfortunately.
There are very few roads that are wide enough for a ROW and that is a problem for transit that is either BRT/LRT.
There is no need for an ROW on Church and to reinterduce Streetcars will be an issue considering the tracks were removed north of Carlton. Where do the tracks run to north of Carlton?
Unless the City is perpare to start taking a lane away from the current traffic, you will have to run in mix traffic for transit.
Going north of Bloor for the Spadina line ROW will not happen due to the road as well load factor.
If you think the SOS mess was bad for St Clair, it will be twice for Spadina Rd LRT.
The road that needs an LRT right now is Dufferin St, as it sees 47,000 riders a day.
It has 3 problem area just to try to put an LRT in mix traffic now. To put an LRT on Dufferin will cost $50 million per Km to deal with the 3 trouble areas. This is from CNE to Steeles.
How do you put an ROW on Dufferin St without removing a lane of traffic?
St Clair has a problem now just to extend the ROW west of Gunns loop.
Removing a lane of traffic off St Clair west of Runnymede for the ROW will have some impact on traffic, but not that much outside of peak time. Even then it will not be that bad.
Between Runnymede and Symes Rd is the major issue.
I know this first hand as I had have walk and taken photos of this area.
I can hear Wal-Mart yelling already and the EA has yet to start. Look for it in 2007.
Another problem is the CP bridge at Scarlett Rd as the 512 is to connect with Kipling. The city has no ROW or height in the plans for a new bridge to support an LRT at this time.
512 will connect to MT Dundas LRT at Kipling.
