UnderAlternatives B2 and B4, construction of new or modified intersections would meet all RIDOT requirements.In 2015, Alternative B2 would cause one location, the unsignalized driveway of Post Road at Relocated DeliveryDrive, to degrade to LOS E or LOS F.Traffic operations under Alternative B2 are expected to improve at six intersections in 2020 and six differentintersections in 2025 due in part to shifts in regional traffic from roadways throughout the City of Warwick toFully Relocated Airport Road. Improvements are also attributed to the optimization of signal timing at anumber of intersections throughout the Study Area.In 2025, Alternative B2 would result in one intersection (Main Avenue at Jefferson Boulevard) continuing tooperate to LOS E or LOS F, compared to the No-Action Alternative. Also in 2020 and 2025, Alternative B2 wouldcause two unsignalized driveways along Post Road to degrade to LOS E or LOS F. The intersection of Post Roadat Relocated Delivery Drive does not exist under the No-Action Alternative but is projected to operate at LOS Eor LOS F under Alternative B2. The signalized intersection of Post Road at Donald Avenue is currentlyoperating at LOS D and is projected to degrade under the No-Action Alternative to LOS E or LOS F. UnderAlternative B2, the signal would be removed and the intersection would degrade to LOS E or LOS F.Chapter 5 - Environmental Consequences 5-144 July 2011\\mawatr\ev\09228.00\reports\FEIS_Final_July_2011\PVD_CH05_Environmental_Cons_JUL_2011.doc
