Minimum Problem Statements – Highway – 10 <br />The section of Old NC 86 (SR 1009) from I-40 to Dairyland Road is currently a two-lane, 20 to 24-foot <br />undivided cross section with right and left-turn storage at various intersections. The section of Old NC 86 <br />from Dairyland Road to Old Fayetteville Road is currently a two-lane, 20 to 24-foot undivided cross <br />section that widens to a 30 to 40-foot undivided cross section with a center two-way left turn lane <br />transitioning to left-turn storage at two intersections. <br /> <br />Additional vehicle lanes would affect the character of the roadway and likely impact residential and <br />agricultural areas. Bike lanes along the segment between Hillsborough Road and Dairyland Road would <br />improve the corridor, as this segment of roadway sees very heavy bicycle traffic at certain times. The <br />road is narrow and it can be difficult for vehicles to pass bicyclists when there is traffic, and bicycle lanes <br />would alleviate this pressure. There are existing turn lanes at major intersections along the entire <br />corridor, but other safety improvements would also ease congestion in the future. <br /> <br />The CTP designates the roadway as needs improvements. The project proposal is to provide a two-lane <br />undivided cross section comprised of twelve-foot travel lanes and five-foot bike lanes to more safely and <br />efficiently accommodate increasing traffic volume and facilitate bicycle travel. <br /> <br />NC 98 (Holloway Street and Wake Forest Highway) (US 70 to Wake County Line) <br /> <br />NC 98, from US 70 to the Wake County boundary, is currently a four-lane undivided road from US 70 to <br />Nichols Farm Drive and a two-lane section east of the intersection with Nichols Farm Drive. The short <br />section from US 70 to Junction Road is already five lanes and will receive capacity improvements as part <br />of the East End Connector construction that is already in progress. There are two possible project <br />sections: Junction Road to Nichols Farm Drive; and Nichols Farms Drive to the Wake County Line. There <br />are commonly turn lanes at cross streets, center left turn lanes at some retail developments and turn <br />and acceleration lanes at driveways to major subdivisions. Sidewalks and bike lanes are rare and mostly <br />concentrated in the segment near US 70. NC 98 is the principal road between Durham and northern <br />Wake County (including Wake Forest) because Falls Lake limits the number of roadways that can make <br />this east-west connection. It is the only major east-west roadway between I-85 and I-540, which is ten <br />miles or more, and these rural areas are likely to experience substantial residential growth over the next <br />few decades. The CTP includes the addition of a narrow median in the current four-lane section and the <br />addition of two travel lanes in the current two-lane section to create a four-lane divided boulevard <br />throughout. <br /> <br />The 2011 AADT for the four-lane segment of NC 98 ranges from 16,000 vpd to 24,000 vpd, and thus only <br />the segment near US 70 is approaching the 24,000 vpd LOS D capacity. The 2040 volume, however, is <br />projected to range from 24,000 vpd to 39,000 vpd. This will create volume-to-capacity ratios from 1.0 to <br />1.5, an indication of heavy travel delays on a key corridor. The 2011 AADT for the two-lane segment of <br />11,000 vpd, which given the 12,400 vpd LOS D capacity, is creating some delays and safety concerns <br />(e.g., passing vehicles on a two-lane road). The 2040 volume is expected to increase to 18,000 vpd, <br />causing many delays and crashes if additional capacity is not added. Although long-range plans provide <br />for additional lanes on I-85 and I-540, this additional capacity is likely to have little effect in drawing <br />traffic away from NC 98 given the ten plus mile distance between those roadways and the expected <br />residential growth.
