Adelaide Landing Residential Development Traffic Impact Analysis 1/31/2017 In this scenario, no geometric or lane arrangement changes were assumed. As with the 2022 No -Build condition, eastbound and northbound movements along TH 61 record levels of service below acceptable levels. In addition, some side -street movements at TH 61 & 130th Street North begin to experience levels of service below acceptable limits. Conversely, there are improvements in levels of service at some locations. This is a situation that occurs in Synch ro/SimTraffic computer runs on occasion. Due to the variable seeding of the five runs, there are times that the level of service actually records improved operation. The traffic growth to year 2040 exceeds the carrying capacity of a single through lane in each direction along TH 61. Further, at the signalized intersections, the green time for TH 61 traffic must be so long to adequately handle through traffic that the side street queues build as they wait for their short green cycles. This is evidenced as queue lengths exceed available storage at certain locations (e.g., TH 61 at 130th Street, WB right turn, NB and SB left turns; TH 61 at 140th Street, WB left turn, NB left turn, NB right turn). To mitigate these issues, Westwood tested the impact of increasing TH 61 to four lanes (two lanes in each direction, plus reconstructing 130th Street to collector standards (see Table 6). The resulting levels of service fall to generally acceptable levels. This eventuality has been foreseen in the City of Hugo 2030 Comprehensive Plane, as well as the US 61 in Hugo — Corridor Access Management Plan Memorandum of Understanding MOU 3. The 2030 Comprehensive Plan stated, "...With the number of access locations, together with the traffic volume levels, this roadway is approaching the need for expansion to a four -lane facility. In addition to the mainline congestion, queuing at existing signalized and unsignalized intersections provides a source of localized congestion on the City street system." This side -street congestion is evident in the 2022 and 2040 No -Build scenarios. The TH 61 MOU stated that the Corridor Access Management Plan shall occur over time, and that several ongoing factors should be implemented in Hugo, including: Preserving right-of-way for the ultimate four -lane section as land is replatted for development trough dedication or outlots. MnDOT will continue to review the needs on US 61 as part of the agency's long range planning process.
