How much is more regular maintenance, snowploughing, etc? How long do you think it would take to spend the construction cost again in maintenance and reconstruction?20 years it too short. The pavement will have to be redone in 20 years but the bridge structures--which are by far the most expensive part of a freeway project--last for at least 50. Closer to 100 with the newer construction standards. Plus fixing up a bridge or pavement when its lifespan is done is cheaper than building it from scratch, because the corridor is already there. They will not be repaying the entire construction cost every few decades.
