Kraus Development (525-565 Conestogo Road) | 3-35 fl | Proposed

An enclosed bridge means keeping the snow off, and the MTO won't like that snow going on the highway, so it'll need roof drainage. That will probably mean at least somewhat pricy engineering.

Smooth sloped metal roof with just enough heating capacity built in to prevent snow freezing to the surface and building up (let it fall to the road below in pieces small enough not to be an issue for drivers). Done. I mean, it’s not nothing, but in the context of building a bridge across an entire expressway it’s not a significant factor. Anyway, where would the snow that lands on the bridge go if it were an open bridge?
