Been thinking a lot about the grade separations that need to happen in South Edmonton, and I'm wondering how you would do it at the Whitemud Drive ramps and 34th Ave? Did some rough measurements and it appears that you would need at least a 200 m approach for a road-over-rail overpass (based on 50th Street and CPKC rail yard) or a 140 m approach for a road underpass (based on 63rd Ave by Gateway). Between Gateway Blvd and the CPKC ROW, there's barely a distance of 50 meters. Do you build overpasses that completely skip over Gateway Boulevard with no access to the latter? Do you squeeze in more interchanges to maintain that access? Do you adjust the grade of Gateway Blvd at those intersections to allow for a shorter approach to get over/under the tracks (for the Whitemud ramps, you'd have to completely rebuild the Gateway Blvd overpass over Whitemud Drive for this solution)? What about adjusting the grade of the rails? With approaches that are around 380 m long, you could bring the tracks above the grade of the intersections with 5.5 meters of clearance below the rail overpasses, all while the grade is gentle enough for freight and high-speed passenger rail. The space is there for approaches that long, but you have to completely rebuild the tracks, meaning high costs and immense disruptions for freight rail traffic. Plus, the current container yard on 99th Street and 34th Ave will be rendered useless. What do we do?
