ION - Waterloo Region's Light Rail Transit

[ookpik]

Why wouldn't they make this crossing one large complete concrete crossing? 

I realize the rail sections are modular but I also see almost every rail crossing built a significant hazard to cars, bikes and pedestrians as the road beds sinks or lift after only a few years.

Where I am in Austria right now the crossings are made of sections of hard rubber. These have the maker's name moulded into the material so I presume they're a standard design and size. I'd have thought rubber would be more flexible in cold weather and provide cars with a smoother ride when they cross. Maybe rubber doesn't stand up to our harsher winters.
