INTRODUCTION Roadway Engineers and Consultants Inc was employed by the North Carolina Department of Transportation to design a roadway connecting Alexandria and Old Statesville Road and also a Park-n-Ride facility along the Norfolk-Southern Railroad Due to the addition of the Charlotte-Mecklenburg Transit Plan which will locate a rail transit station near Alexandria and Old Statesville Road the surrounding roads will become more populated therefore lowering the level of service below the acceptable limits To alleviate the traffic congestion and raise the level of service of the surrounding roads a roadway was proposed to accommodate the increased trip generation produced by the Rail Transit Station The roadway was to be built connecting Alexandria and Old Statesville Road This new roadway will compensate for the increased trip generation due to the proposed Rail Transit Station and will raise the level of service to an acceptable limit The proposed roadway will connect Old Statesville Road and Alexandria A topographic map is located in Appendix C which illustrates the exact location of the roadway The roadway will be classified as a commercial collector street with a design speed of 40 mph The roadway will include two 12 feet lanes curb gutter and a 16 foot median The proposed roadway design will include a total right of way of 80 feet Due to the layout of the two existing roads being connected a horizontal curve was designed to compensate for the unparallel layout while keeping intersections at both ends perpendicular to the existing roads A vertical curve was also needed due to the elevation changes along the proposed roadway layout The vertical curve was designed to minimize the amount of fill material needed to complete the project This was accomplished by equalizing the amount of cut and fill thus reducing the cost of the project The proposed Park-n-Ride facility will provide access to the Rail Transit Station A detailed plan view of the facility is located in Appendix E
