The ARDOT maintains Highway 115 like all other parts of the state highway system. As a part of these responsibilities, the Department tracks the volume of traffic using its roads in surveys using a metric called average annual daily traffic (AADT). ARDOT estimates the traffic level for a segment of roadway for any average day of the year in these surveys. As of 2018, the peak AADT on the highway was 4,600 vehicles per day (VPD) near the northern terminus in McCrory. All other segments were below 1,000 VPD, with most counts below 400 VPD. For reference, the American Association of State Highway and Transportation Officials (AASHTO) classifies roads with fewer than 400 vehicles per day as a very low volume local road.
