Les- Sorry I should have mentioned the tunnel I was referring to was not in the Villages. They were installing the tunnel for a bike path that was funded many years after the road had been built. The road bridged a set of train tracks and the bike path tunnel went parallel to the track but through the raised earth under the roads approach to the bridge. I did guess at the lengths of the precast, so they might have been longer, and there were quite a few of them.
