Next week, Rt. 236 between South Berwick and Berwick, Maine, will be closed on 10/5 thru 10/6 so that the Rail Road people can replace the track that goes across the road, apparently to improve the safety of the track.  Some have asked for a clearer map of the suggested detour.  Thanks to Google Maps, I've done some screen captures with updates.  Hopefully these maps will help.  Otherwise, if you have a GPS mapping service for traveling, use that to get you around the construction: there are alternative roads.

The first is a composite, followed by the 3 images.  (hope this works!)
