In June 1945 a seismic study was made for the projected Halligan Avenue out, stations 364-374, Route 2 relocation in Shelburne, Mass. Nine profiles were run at this time and a report on this work was submitted by James E. Maynard and Rev. Daniel Linehan (file report of July 1945). As a result of a consultation with the State Engineers in August 1948, the proposed center-line of the road was relocated so as to be in a more favorable position. This new location is shown as alternate center-line number 2 on the plan of the seismic transverses. A cut approximately 1600 feet long is planned between stations 364 and 380. The approximate maximum depths of the cut are:
17 feet at station 365
24 " " " 368+50
23 " " " 371+50
12 " " " 372+50
8 " " " 375+00
Between stations 375+80 and 379+50 the depth of the cut gradually decreases from 8 feet to 0 feet. In order to obtain additional information on subsurface conditions at this site, especially along the segment of the relocated center-line where cuts are to be the deepest, a supplementary program of seismic studies was undertaken.
The work was done in October 1948 as a part of a cooperative program of the Massachusetts Department of Public Works and the United States Geological Survey.
