SUBSURFACE INVESTIGATION, 10TH STREET MALL BRIDGE, SECTION D004, NEW CARROLLTON ROUTE

Results are summarized of seven supplementary test borings made to investigate subsoil conditions at the location of piers of the 10th Street Mall Bridge crossing the Penn Central Railroad tracks adjacent to D Street S.W. in southwest Washington, D. C. The purpose of the exploration was to ascertain the condition of soils immediately overlying the mined tunnels which could have been affected by settlements occurring during the mining operation. The report contains geological sections along the lines of the bridge piers, logs of the test borings, results of laboratory tests performed on samples obtained and a brief text describing results of the investigation.
