Lexington Station Phase 3 Traffic Study February 26, 2021 Page 6 The following information summarizes the operational and/or queueing issues identified as part of the existing capacity analysis: x Lexington Avenue/Red Fox Road: o Southbound left-turn queues extend beyond turn lane storage and into the Lexington Avenue/ I-694 South Ramp intersection approximately 25 percent of the p.m. peak hour. These queues cause friction over the I-694 bridge, as the left-turn queues restrict the thru volume along Lexington Avenue to one (1) lane. o Eastbound left-turn queues extend beyond the Lexington Station east site access approximately 15 percent of the p.m. peak hour. o Westbound right-turn queues extend beyond turn lane storage approximately 25 percent of the p.m. peak hour. x Lexington Avenue/Target Road o The westbound approach operates at LOS F (53 seconds) with a 95th percentile queue of approximately 200 feet (i.e. eight (8) to ten (10) vehicles) during the p.m. peak hour. Planned Transportation Improvements Ramsey County has programmed a reconstruction project for Lexington Avenue from County Road E to I-694. The reconstruction project includes replacing aging and deteriorating pavement, replacing traffic signals, and improving pedestrian and bicycle facilities. As part of the reconstruction project, Lexington Avenue will be converted from a 5-lane undivided roadway to a 4- lane divided roadway with left- and right-turn lanes. Dual southbound left-turn lanes and an eastbound right-turn lane are planned to be constructed at the Lexington Avenue/Red Fox Road intersection, which are expected to mitigate existing queuing issues at the intersection. In addition, access management strategies will be implemented along the corridor. The Lexington Station access on Lexington Avenue is expected to be closed, and the Arby’s/Big O Tire’s access will be limited to a right-in/right-out. In order to provide access to these existing developments, the Lexington Avenue/Target Road intersection will be reconstructed to provide a west leg. The reconstruction project is expected to be completed by 2023, therefore, for the purpose of this study, the reconstruction project was assumed under year 2023 no build and build conditions. Note that the reconstructed Lexington Avenue/Target Road intersection is being designed for future traffic signal control, however, the timing of this traffic control improvement is unknown at this time. Since the Lexington Avenue/Target Road intersection is the primary access to the development, the roadway network was evaluated with and without traffic signal control at this study intersection.
