100 <br /> the I-85/US 70 Connector approximately 400' north of the existing Ben Johnston Road <br /> and two right in-right out accesses on what is described in the study as a service road <br /> resulting from the modification of the existing braided interstate interchange via removal <br /> of the existing westbound 160 exit ramp. A full movement access on Mt. Willing Road <br /> directly across from Turner Street is proposed in phase 2. <br /> Interstate Interchange Modifications: <br /> As previously noted, the traffic study includes recommendations for modification of the <br /> existing westbound I-40/85 braided interstate interchange with removal of the existing <br /> westbound exit 160 ramp resulting in conversion of the braided configuration to a one- <br /> way service road providing access to Mt. Willing Road via reassignment of traffic <br /> currently using this exit 160 to the 161 exit ramp and utilizing the resulting service road <br /> to access Mt. Willing Road. Site access to the resulting service road in the form of two <br /> right in-right out driveways is proposed. NCDOT staff is in general agreement with the <br /> conclusion in the above-referenced weaving assessment that the current configuration is <br /> not desirable due to the presence of a high speed conflict point at the existing exit 160 <br /> gore and the relatively short weaving length provided by the existing braided ramps. Staff <br /> also concurs that operational and safety problems will worsen with the increase in traffic <br /> associated with the proposed development and/or future traffic growth. The proposed <br /> modification of the interchange and the proposed break in the controlled access right of <br /> way to accommodate the proposed site accesses will require review and approval by the <br /> NCDOT Right of Way Disposal and Controlled Access Committee as well as the Federal <br /> Highway Administration. The Applicant has not yet made the necessary submittals to <br /> these bodies; therefore, the outcome of this proposal is not determined at this time. The <br /> remaining comments in this letter are based on the presumption that the modification will <br /> proceed as proposed and contingent upon approval. In the event that the request is not <br /> approved, additional traffic operational analysis for alternate scenarios will be needed. <br /> Required Road Improvements: <br /> As a condition of the pending NCDOT Driveway Permit and contingent upon approval of <br /> the interstate interchange modification and controlled access breaks as described above, <br /> the Applicant will be required to construct the following road improvements to mitigate <br /> traffic impacts attributable to site traffic to ensure acceptable operation. <br /> Phase 1 Improvements: <br /> The following improvements shall be constructed with development of phase 1 and prior <br /> to placing the proposed gas station with convenience store into operation. <br /> Intestate Interchanjze Modification: <br /> Subject to FHWA approval, modify the existing interchange as follows: <br /> • Remove existing westbound 160 exit ramp <br /> • Reconfigure to provide for a one-way service road with dual thru lanes extending <br /> from the 1-85/US 70 Connector to the westbound 160 on ramp and proceeding as <br /> a single thru lane to Mt. Willing Road <br />
