Buc-ee’s Phase 2 – Efland, NC <br /> <br />23 <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). <br /> <br />The following improvements are committed with build-out of Phase 1 of the Buc-ee’s – West <br />Orange County development and were assumed to be in place in the background and build-out <br />conditions: <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 <br />Service 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 committed improvements in place, the intersection is projected to operate at LOS B in <br />the AM peak hour and LOS C in the PM peak hour with or without the project in place. <br />SimTraffic simulations indicate that queues are expected to be manageable and accommodated <br />within the recommended storage lengths. Therefore, no additional improvements are <br />recommended at this intersection to accommodate site traffic. <br /> <br />Table 6.6 summarizes the operation of the intersection for the existing (2020) 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 />Existing (2020) Traffic (Unsignalized)* WB – A (3.2) WB – A (3.7) <br />Background (2023) Traffic (Unsignalized)* B (14.9) C (23.3) <br />Build-out (2023) Traffic (Signalized) B (14.7) C (23.9) <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 />469
