Geologic interpretations of seismic data relocation Routes 15 and 20 in Sturbridge, Mass.

The proposed improvements at the junction of Routes 15 and 20, Sturbridge, Massachusetts, requires a cut of considerable magnitude for the relocation of east-bound Route 20 between stations 158 and 167. Geologic and seismic studies were made of the site for the purpose of determining the position of the bedrock surface, the kinds of material to be excavated, and the relationships of these materials to each other.

The work was performed in November 1949 as a part of a cooperative program of the Massachusetts Department of Public Works and the United States Geological Survey.
