At this site the reconstruction of Route 1 requires a deep excavation through a high, east-west elongated hill. In order to obtain subsurface information that would be of aid in selecting the most suitable location for this deep cut through the hill, geologic and seismic studies were made in October 1949. The work was done as part of a cooperative program of the Massachusetts Department of Public Works and the United States Geological Survey.
