22 <br /> <br />• After completion of the FM Diversion Project, regrade/asphalt surface county highways that match up <br />with structures over the FM Diversion. Highways south of I94 will tie into Cass highway 15 and highways <br />North of I94 will tie into Cass highway 11. <br />• Repair, replace, or remove all bridges/structures identified as poor or severely load rated. As well as any <br />structures within the FM Diversion footprint. <br /> <br />Long-Range (2034 to 2043) <br />• Continue to complete asphalt overlays on pavement that is at or near 20 years of life. <br />• Continue with our plan to regrade all paved County Highways that are narrow and have steep inslopes <br />to improve safety by adding shoulders, flattening inslopes, and constructing improved intersections. <br />• Replace/reline existing centerline pipe under our county highways that are 50 years or older. <br />• Construct a continuous paved highway running east-west across the County south of Interstate 94. <br />• Continue with our plan to regrade/reshape all gravel roads to ensure we maintain a proper 28-foot-wide <br />surface, maintain 4:1 inslopes, and maintain ditch drainage and culverts. <br />• Work towards having no load posted bridges on our County Highway system. <br />2024-2028 Highway Improvement Plan <br />There are numerous factors that can be and are used to make decisions regarding improvements and <br />maintenance on the County Highway System. Many variables go into prioritizing future projects such as average <br />daily traffic as obtained from the NDDOT and/or the FM Metro COG, PCI ratings, asphalt thickness, last year <br />paved, last year sealed, population within the proximity, and points of commerce or increased traffic. These <br />variables are taken into consideration when scheduling the most efficient construction schedules in upcoming <br />years. <br />Many factors are used to make decisions regarding improvements and maintenance of our gravel road system. <br />Routine maintenance, motor grader operations, and annual gravelling programs are sufficient in maintaining a <br />consistent, high quality gravel road. However, there are times where excessive moisture, poor drainage, soft <br />subgrade, and other issues must be addressed. In addition, there are times when major reshaping or regrading <br />of gravel roads must occur. <br />Cass County is proactively working to reduce soft roadbeds through drain tile and subgrade repair/cement <br />stabilization. In addition, Cass County will address significant soft spots and subgrade issues through near term <br />drain tile and subgrade repair projects. Long term work will be done to reshape gravel roads that have become <br />widened or flattened over time from traffic, and up to 15 miles of gravel road will be reshaped annually. This <br />reshaping will save money over time by reducing the width of the roadway back to County design standards, <br />which in turn reduces the overall gravel required to resurface the roadway. <br />Over the last 10 years Cass County has implemented a plan to stabilize and improve gravel road performance. <br />This has been through completing road reconstruction, cement treated subgrade, and gravel stabilization with <br />dust control. This has helped improve many roads, but additional work is needed on our gravel roads to replace <br />culverts, regrade ditches, and improve the roadway. If additional funding becomes available it would be ideal to
