MnDOT District 4 TH 27 / 1-94 Corridor Study MnDOT District 4 selected HR Green to conduct a corridor assessment for TH 27/CSAH 46 in Douglas County, on the west side of Alexandria at the interchange with 1-94. Tasks on the project included, data collection (including traffic counts), traffic forecasts and an Intersection Control Evaluation, public involvement, evaluation criteria, business access evaluation, development of alternatives, cost estimates, and presentation of recommended alternative in a Corridor Assessment Report. As part of the study, HR Green developed concepts for new interchange types, roundabouts, signing improvements, and detour routes. Freight haulers were an important stakeholder in the project, so alternative concepts were especially focused on addressing large truck safety and mobility needs. A scan of environmental issues was incorporated into the evaluation in order to evaluate potential project development and funding issues. HR Green facilitated a public meeting by developing and mailing a postcard to all surrounding residences and business owners. Because the project was partially funded by Douglas County, HR Green prepared planning elements that were intended for implementation by the County: this included improved signing for local traffic circulation and a presentation to the County Board detailing the project outcomes and benefits to the County. MnDOT - District . TH 6o Corridor study - LAKE Crystal HR Green is preparing a Purpose and Need study for MnDOT District 7 on Highway 60 in Lake Crystal. The project includes an analysis of corridor issues and long-term investment planning to determine a preferred alternative to be constructed in 2024. The study includes evaluation of alternative intersection improvements (roundabout, RCUT, Continuous T, and off -set T) through traffic studies and simulation through a VISSIM model. An evaluation of the lone bridge in the corridor is included in the study to determine if removal is an appropriate option. City and County stakeholders are included in the study due to local road impacts and proposed pedestrian improvements. HR Green will prepare a MnDOT geometric layout of the preferred alternative, to be complete in November 2020. MnDOT - District 3 TH 10 Traffic Study MnDOT District 3 selected HR Green to conduct a Traffic Study in the City of Big Lake. The TH 10 Traffic Study examined traffic operations at five intersections of TH 10 in Big Lake to help MnDOT identify a preferred access improvement concept and resolve a long-standing question with the City of Big Lake regarding desire for a new traffic signal on TH 10. The study was structured with an analysis of existing and future conditions, using VISSIM modeling, to determine access control recommendations and intersection treatments. Major tasks included: coordination and meetings with the City of Big Lake, developing design hour traffic volumes, traffic operations analysis, geometric/traffic control alternatives, traffic simulation with VISSIM, and screening to a preferred improvement plan. Reduced Conflict Intersections were a significant feature studied for this corridor. HR Green's roundabout concept that became the preferred alternative.
