SUBSURFACE EXPLORATION PLAN

Location: The subsurface investigation will be conducted along the Natchez Trace Parkway approximately between Milepost 86 and Milepost 114, in Hinds and Madison Counties, Mississippi.

Description: EFL Pavements Branch is proposing to collect seventy-two (72) pavement cores/soil borings to a depth of 10-ft below ground surface to determine the depth of pavement section, aggregate base thickness and subgrade soil properties at the locations shown in table and figures below. The first fifty-six (56) pavement cores and soil borings are along the mainline, the remainder of the borings will be located at the ramps to I-20, HWY 49, and I-55 respectively.

Traffic Control:

A mobile lane closure operation with flaggers will be needed during most of the drilling operation. Traffic control details will be arranged in coordination with Park prior to drilling/coring activities.
