Traffic Study Lexington Avenue Reconstruction Alliant No. 118-0186.0 1 April 18, 2019 1.0 Introduction Ramsey County, in cooperation with the City of Arden Hills and the City of Shoreview, has programmed a year 2020 reconstruction of Lexington Avenue (County State Aid Highway 51) between I-694 and County Road E (CR E). Key aspects of the project include pavement rehabilitation, providing geometric improvements that accommodate pedestrians/bicyclists/transit users, traffic signal upgrades/geometric improvements at the Red Fox Road and Grey Fox Road intersections, and a proposed traffic signal at the Target South intersection (see Figure 1: Project Location). Ramsey County has identified the need to conduct a traffic study along the Lexington Avenue corridor to determine the most appropriate forms of access, lane geometrics, and traffic signal improvements. 1.1 Purpose and Need The purpose of this traffic study is to determine the future vision for the Lexington Avenue study corridor in terms of access, lane geometrics, and traffic signal improvements. Understanding the nature of any corridor safety problems and the need to address potential future traffic operations deficiencies, Ramsey County desires improvement solutions that accomplish the following goals: x Improve or maintain the intersection level of service into the future x Reduce the frequency of severe crashes; and x Provide access management recommendations to improve overall traffic flow To support Ramsey County in identifying the appropriate improvements that meet the above stated goals, this traffic study accomplishes the following: x Documents the existing geometric, traffic operations, and safety characteristics x Documents design year 2020 and horizon year 2040 traffic forecasts based upon study area historical traffic volumes and expected population growth x Develops and evaluates high-level conceptual alternatives that will improve intersection safety characteristics to a varying degree x Conducts a traffic operations and safety analysis of each alternative x Identifies a preferred alternative 1.2 Description of Location The subject of this study is the Lexington Avenue corridor between I-694 and CR E, and in particular, the intersections with Red Fox Road, Target South, and Grey Fox Road. The study area is composed primarily of retail and service related land uses with access to a small residential neighborhood (approximately 50 houses) via Grey Fox Road.
