Northfield / 85 Exchange upgrades?

My bad. It's 30m for railway crossings and 150m for bridges, etc. 143 Highway Traffic Act of Ontario.

(d) within 150 metres of a bridge, viaduct or tunnel where the driver’s view is obstructed within such distance.

Suggesting that if the view is not obstructed, the limitation might not apply at all. Which only makes sense. Depending on the design of the bridge and the surroundings, it might not even be obviously a bridge. There are places in Toronto where the road crosses the subway on a bridge, but the area on both sides of the bridge has been decked over so the subway is no longer visible at all.
