1950, Open-File Report 50-52
Three segments of the proposed relocation of Route 116, stations 7 to 135, in Cheshire, Mass. require shallow cuts. For the purpose of obtaining information on the depths to bedrock, and on the nature of the overlaying materials, seismic and geologic studies were made of the segments in October 1949....

This investigation was undertaken to determine the surface and subsurface conditions between stations 25 and 36 of the proposed relocation of the Newburyport Turnpike, Route 1, Topsfield, Mass. Reconnaissance seismic work was performed at the site in September 1949. Because that work showed bedrock near the surface over an extensive...

1950, Open-File Report 50-44
The proposed relocation of the Concord-Westminster Highway, Route 2, in Lancaster, Mass., requires a long, deep cut between stations 138 and 155. A preliminary seismic survey was made of the site in October 1949. At that time five transverses were made along the base-line, and three transverse to it. This...
