No project has been implemented to date because of numerous obstacles to construction (including the aqueducts and very poor soils), difficulties in securing environmental permits, and lack of public support for any of the proposed alignments. 5.1 No-Build Alternate The No-Build Alternate includes no upgrades to the existing roadway other than potential future overlays on existing pavement. This alternate does not improve congestion, safety, or geometrics or provide an adequate east/west corridor. Therefore, the No-Build Alternative would not correct the current deficiencies identified and as a result is not a feasible alternative. 5.2 Signalize the Existing County Road IILexington Avenue Intersection The intersection configuration of County Road I at Lexington Avenue currently consists of two T -intersections separated by 400 feet. The south intersection, which includes County Road I to the east, is controlled by an all-way stop. The north intersection, which includes County Road I to the west, has a stop condition for eastbound County Road I. Each of these T-intersections was analyzed to determine if warrants are met for the installation of a traffic signal. Based on traffic counts by Ramsey County, sufficient traffic volumes exist on westbound County Road I to warrant the installation of a traffic signal at the south intersection. If the existing geometrics are left in place the intersection could be signalized with the following two options: Signalize the South Intersection Only The first option is to signalize just the south intersection. This will have a detrimental effect on both Lexington Avenue through traffic and the north intersection turning movements. Southbound Lexington Avenue traffic will frequelltly back up past County Road I to the west, especially in the a.m. peak hour. This will make entering Lexinglon A venue from the west even more difficult than it is today. Also northbound Lexington Avenue traffic will have a difficult left turn onto westbound County Road I because it is immediately north of the traffic signal at an uncontrolled intersection. Signalize Both Intersections Another option is to signalize bolh T -intersections as one system. This will also have a detrimental effect on Lexington A venue through traffic. The offset will require that ,iY k!)i:d! ~()\H ;'" '~" ',1 i )~'.\,,-' j, 'j ;;E'n! hli~~: ;.. I
