Key Findings and Recommendations <br />Based on the results of the of the existing and future year analysis which was completed for the CSAH <br />5 Corridor Traffic Study, four intersections along the CSAH 5 corridor were considered in the <br />development of improvements to address capacity and safety performance. These intersections <br />include: <br />• CSAH 5 and CSAH 63 (Green Valley Road and 175th Avenue) <br />• CASH 5 and 167th Avenue NW <br />• CSAH 5 and CSAH 56 (Ramsey Boulevard) <br />• CSAH 5 and Sunwood Drive <br />The following key findings and recommendations for each of the four intersections along CSAH 5 <br />were developed as a result of the CSAH 5 Corridor Traffic Study <br />CSAH 5 and CSAH 63 <br />An elevated crash history was observed at both the east and west intersections of CSAH 5 and CSAH <br />63. Traffic volumes are anticipated to increase at these intersections as the surrounding area develops. <br />Additional turn lanes will reduce the conflicts and crash risks under future year conditions. <br />Furthermore, the installation of lighting will help alert drivers to the intersections at night. The <br />marginal costs of the proposed improvements at this intersection would potentially decrease if the <br />improvements are coordinated with future corridor investments. <br />Recommendation: Implement turn lane improvements and lighting as part of the next preservation <br />investment to improve safety and modernize intersections to support future growth. <br />CSAH 5 and 167th Ave NW <br />167th Avenue NW functions as an east -west roadway. Higher crash rates were observed at the CSAH <br />5 and 167th Avenue NW intersection compared to the majority of the intersections along the CSAH <br />5 corridor. The roundabout concept was found to be the most cost-effective improvement for this <br />intersection with an estimated 12-year return on investment. <br />Recommendation: Implement a roundabout as part of the next preservation investment to improve <br />safety and serve the function of 167th Ave as an east -west corridor. <br />CSAH 5 and CASH 56 (Ramsey Blvd) <br />An elevated crash history was observed at the CSAH 56 (Ramsey Boulevard) intersection, including <br />injury crashes. The traffic volume from northbound CSAH 56 to northbound CSAH 5 is expected to <br />increase with the completion of the interchanges on US Highway 10. Turn lane and roundabout <br />concepts were considered for this location; both concepts have a similar construction cost, <br />approximately $3,000,000, and impacts to surrounding land use. The roundabout concept provides <br />3 <br />
