The horizontal datum is NSRS NAO 83 (20 I 11 Epoch 20 I 0.

The vertical datum is the average of the mean lower low water soundings, in feet, observed over the National Datum Epoch as shown on NOAA Navigational Chart 122£15 69th Ed., Feb. 2017.

The historic boring locations are approximate and based on record drawings of the original, 1950s, crossing and the second, 1970s, crossing.

Investigation locations indicated are approximate. Contractor to confirm locations of utilities and underground infrastructure with utility owners and with VDOT prior to commencement of work. The Contractor shall propose changes to investigation locations for the acceptance of the Engineer as required to safeguard existing utilities and underground infrastructure.

Vane shear test (VSTl and flat plate dilatometer (OMTl profiling locations shall be offset a few feet from the adjacent cone penetration test (CPTl or seismic cone penetration test (SCPTl location.
