Great, but if they build their bridges anything like they build their escalators, we will be seeing a video titled "deadly bridge collapse" some time in the next few weeks on LiveLeaks! :p

It's a Rapid Bridge replacement. They have replaced several of the bridges on the 417 through Ottawa with this method.
Build new bridge at a location close to old span.
Prep, lift and remove old span, by removing guardrails, bolts etc.
Move new span into place via SPMT, or similar and reconnect.
The prep takes a few months the actual move can be completed in a night if the span is small enough.
