Summary of Interim Findings – AM Peak With three‐lane work zone pattern, 10‐20% diversion will keep average travel speed over 40mph With optimum diversion (equilibrium), network model estimates I‐40 westbound travel time to increase through work zone from 8.6 to 12.7 minutes for three‐lane pattern Model estimates 33% diversion for three‐lane pattern Model estimates volume increases over 500vph for Wade Avenue, US64, US1, and NC55 Diversion from I‐40 estimated to result in travel time increases over 30% for I‐440 EB, US70 northbound, Hammond Rd. northbound, and Rock Quarry Road westbound 25

Summary of Interim Findings – PM Peak With three‐lane work zone pattern, 40mph average travel speed can be maintained with approximately 30‐40% diversion. With optimum diversion (equilibrium), network model estimates I‐40 eastbound travel time to increase through work zone from 8.6 to 13.9 minutes for three‐lane pattern Model estimates 36% diversion for three‐lane pattern Model estimates volume increases over 500vph for US70, and over 1,000 vph for US64, US1, and NC55 Diversion from I‐40 estimated to result in travel time increases over 30% for Wade Ave. EB and Davis Drive SB 26
