Buc-ee’s – Efland, NC <br /> <br />25 <br /> <br />6.6 US-70/I-40 Connector – I-40 WB Ramps <br /> <br />Analyses indicate that unsignalized intersection of US-70/I-40 Connector – I-40 WB Ramps <br />currently operates with short delays on the minor street approach (I-40 WB Ramp) in all peak <br />hours. The minor street approach is expected to continue operating with short delays in the <br />background condition. <br /> <br />The following improvements are recommended to accommodate projected site traffic demands: <br /> <br />• Restripe the existing westbound left-turn lane on I-40 WB Ramp to provide an exclusive <br />through lane <br />• Construct a westbound shared through/left-turn lane with 450 feet of storage and an <br />appropriate taper on I-40 WB Ramp <br />• Widen the I-40 WB Ramp to provide dual westbound right-turn lanes with 450 feet of storage <br />and appropriate tapers <br />• Construct a second receiving lane on I-40 WB ramp departure, extending to I-40 WB Service <br />Road <br />• Extend the existing northbound left-turn lane to provide a continuous left-turn lane and a <br />continuous through lane on the northbound approach of US-70/I-40 Connector <br />• Install a traffic signal <br /> <br />With the recommended improvements in place, the intersection is projected to operate at LOS B <br />in the weekday AM peak hour and the Saturday peak hour and LOS C in the PM peak hour of the <br />build-out traffic condition. SimTraffic simulations indicate that queues are expected to be <br />manageable and accommodated within the recommended storage lengths. Therefore, no <br />additional improvements are recommended at this intersection to accommodate site traffic. <br /> <br />Table 6.6 summarizes the operation of the intersection for the existing (2019) and projected <br />(2023) background and build-out traffic conditions. <br /> <br />Table 6.6 <br />Level-of-Service <br />US-70/I-40 Connector – I-40 WB Ramps <br />Condition AM Peak Hour <br />LOS (Delay) <br />PM Peak Hour <br />LOS (Delay) <br />Saturday Peak Hour <br />LOS (Delay) <br />Existing (2019) Traffic – <br />Unsignalized* WB – A (3.1) WB – A (3.7) WB – A (2.7) <br />Background (2022) Traffic – <br />Unsignalized* WB – A (3.0) WB – A (3.2) WB – A (2.7) <br />Build-out (2022) Traffic – <br />Signalized B (14.9) C (23.1) B (18.7) <br />* Note: HCM methodology does not report an overall level of service for unsignalized intersections. The level of <br />service and delay for the worst approach (per SimTraffic) are reported above for unsignalized intersections. <br />146
