CASS COUNTY ROADWAY 18 EXTENSION STUDY – CASS COUNTY, ND 26 5 PURPOSE AND NEED 5.1 PROJECT PURPOSE The purpose of this project is to study the feasibility of extending CR 18 from CR 17 to CR 15 and transitioning ownership to a county roadway and the roadway typical section to meet county roadway standards. As a part of this project, existing and future needs, as well as, necessary improvements to the study corridor are being analyzed in order to provide recommendations and alternatives to decision makers regarding the future of this corridor. As an outcome of this study, the intent is for CR 18 to become a functionally classified roadway if 52nd Street SE is converted from a township roadway to a county roadway. The goals associated with this project are as follows:  Study the county roadway network connection for CR 18 between CR 17 and CR 15 to maintain a roadway network that allows users to travel on a standard roadway cross-section to Kindred and between CR 15 and Interstate 29.  Provide recommendations/alternatives for a roadway that maintains a suitable driving surface throughout the year and accommodates traffic mix consisting of passenger cars, heavy trucks, and agriculture implements.  Provide recommendations/alternatives that will minimize the potential for crashes along the corridor.  Support the goals and objectives of the Cass County Transportation and Comprehensive Plan The sections that follow describe the existing conditions summary along the project corridor and the needs of the project. 5.2 EXISTING CONDITION SUMMARY 5.2.1 ROADWAY TYPICAL SECTION AND ATTRIBUTES Within the project study area, 52nd Street SE is an aggregate roadway with a width of 28 to 30 feet and open ditch drainage. The Normanna and Pleasant Townships maintain 52nd Street SE with annual aggregate resurfacing at a variable rate between 150 cubic yards per mile (CY/mile) and 365 CY/mile. The typical sections for the existing 52nd Street SE and CR 18 are shown in Figure 2. Driveway and field access locations along both 52nd Street SE and CR 18 typically have corrugated metal pipe culverts for drainage. Flood protection measures have been implemented on the east end of the study area. The measures include levees and sluice gates installed on the north side of the roadway. Approximately 0.75 miles west of the Sheyenne River bridge, two transverse corrugated metal pipe culverts cross 52nd Street SE providing conveyance for a tributary of the Sheyenne River. The 52nd Street corridor speed limit is 55 miles per hour (MPH) except for reduced speed zones of 40 MPH approaching the Sheyenne River bridge and 25 MPH immediately adjacent to the bridge. The 52nd Street SE intersection with CR 15 has two-way stop-control on the 52nd Street SE approaches and the intersection with CR 17 is controlled by a yield sign on the 52nd Street SE approach and stop sign on the CR 18 approach. Several north-south township roadways intersect with 52nd Street SE throughout the project study area. The north-south township roadways are typically yield controlled with yield signs
