Challenges

The Davenport Diamond is one of the busiest train crossings in North America, where CP Rail's North Toronto Subdivision intersects with Metrolinx's Barrie rail corridor.
The at-grade rail-to-rail crossing is very similar to a four-way intersection found on most city streets, with traffic signals directing trains in the same way that traffic lights guide cars.
The project will grade separate the railway tracks by elevating the north-south Barrie rail corridor tracks over the Davenport Diamond, eliminating the intersection and train traffic conflicts.
The project is technically challenging. The site location is within a dense urban environment in Toronto and will affect over one kilometer of rail in each direction, which will have an impact on the traffic flow of municipal roads. The project is located in a very tight, 66-foot-wide rail right-of-way, with adjacent buildings on both sides of the corridor.
Employing appropriate construction staging and methodologies for construction in an active rail corridor with limited access point and staging areas.
Upholding expectation of Authorities Having Jurisdiction (AHJ) as it relates to an overall design excellence and aesthetic vision.
Adherence to local/regional bylaws and obtaining and complying with all required permits, approvals and agreements.
Coordination with municipal and 3rd party utility companies for utility relocations.
