Buc-ee’s – Efland, NC <br /> <br />24 <br /> <br />6.5 US-70/I-40 Connector – I-40 EB Ramps <br /> <br />Analyses indicate that unsignalized intersection of US-70/I-40 Connector – I-40 EB Ramps <br />currently operates with short delays on the minor street approach (I-40 EB Ramp). The minor <br />street approach is expected to continue operating with short delays in the background condition. <br /> <br />The following improvements are recommended to accommodate projected site traffic demands: <br /> <br />• Restripe the existing eastbound right turn lane and remove right turn channelization on the I- <br />40 EB Ramp to provide a continuous shared left/through/right-turn lane <br />• Widen the I-40 EB Ramp to provide and exclusive eastbound left-turn lane with 400 feet of <br />storage and an appropriate taper <br />• Extend the existing exclusive southbound left-turn lane on US-70/I-40 Connector to provide <br />400 feet of storage and an appropriate taper <br />• Construct an additional northbound receiving lane on 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 C <br />in the weekday AM and PM peak hours and LOS D in the Saturday peak hour of the build-out <br />traffic condition. All approaches are expected to operate acceptably. SimTraffic simulations <br />indicate that queues are expected to be manageable and accommodated within the recommended <br />storage lengths. Therefore, no additional improvements are recommended at this intersection to <br />accommodate site traffic. <br /> <br />Table 6.5 summarizes the operation of the intersection for the existing (2019) and projected <br />(2023) background and build-out traffic conditions. <br /> <br />Table 6.5 <br />Level-of-Service <br />US-70/I-40 Connector – I-40 EB 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* EB – A (9.3) EB – A (7.5) EB – A (3.9) <br />Background (2022) Traffic – <br />Unsignalized* EB – A (9.3) EB – A (7.5) EB – A (4.0) <br />Build-out (2022) Traffic – <br />Signalized C (30.6) C (34.5) D (40.8) <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 /> <br /> <br />145
