During the construction of Taxiway A,a portion of Taxiway C was removed from the ramp due to it being deemed a"hot spot"by the FAA. With the removal of this connection,the airport lost access to Taxiway C,Runway 8/26, and Runway 35 from the south end of the apron. This new connector taxiway will give access to Taxiway A, Taxiway C,Runway 8/26,and Runway 35 from the south apron and will help the control tower move aircraft on the airfield especially during busy times. Although the overall quantity of the item did increase,renegotiation of the original unit price is not needed.
