Any activities over Metrolinx corridor requires flagging protection/working at night. It’ll be a pain to coordinate construction activities and any future maintenance/inspection work around rail traffic. Not saying is impossible for the City/MTO and Metrolinx to work together and sign some...

If you want to know which sections of the Gardiner superstructure has been rehabilitated, just see whether the deck has new concrete barrier wall or the old curb wall and railing. The next phase will be from Grand Magazine St to around Spadina. Pre-engineering work (surveying) has already...

I am not 100% sure this is the reason but dividing the span into two spans allow a shallower bridge deck. This gives you more vertical clearance to the roadway below without having to adjust the grade of the track or the road (which is expensive)

In terms of price, I think FRP and stainless reinforcements are somewhat similar, stainless steel might even be more expensive. There are some constructability issues with FRP bars because they are very brittle compared to steel. They are hard to bend and are almost impossible to be field bent...

There are a couple new details that should make the structure more durable: - Stainless steel are being used in areas prone to chlorine penetration (i.e. top of the deck, barrier walls, pier caps) - Concrete deck waterproofing - Elimination of deck expansion joints to prevent water leakage into...
