Traffic Engineering Study Horizontal Clear Zone Requirements Monitor Road north of Platte River Drive 2022-01-03 Minimum Construction Standards for New and Reconstructed County Roads The Rules and Regulations of the Board of Public Roads Classification and Standards as administered by the Nebraska Department of Transportation,sets standards for New, Reconstructed and 3R work on county roads. The standards for county roads cover many facets and design characteristic for a roadway such as design speed, lane width,shoulder width,vertical &horizontal alignment,cross slope,shoulder slope, horizontal clear zone,and bridge width &capacity. The standards apply to any new construction, reconstruction, or 3R(resurfacing, rehabilitation or restoration) of county roads.The standards that apply to local roads are attached.A section from the standards on Remote Residential Roads is also attached for reference. Maintenance Standards The above rules also have standards for maintenance that concentrate on definitions for what is considered as maintenance such as reshaping, patching, resurfacing,reshaping drainage,cleaning&repairing culverts, mowing, replacement of structures in-kind,etc. Roadway Characteristics Monitor Road north of Platte River Drive is a gravel county road classified as a local road with very low traffic. The road is straight and flat. The road serves one occupied residence with a driveway off Monitor Road at approximately 4,000 feet north of Platte River Drive. North of that driveway,the road narrows to a one lane roadway. The roadway was opened for one mile north of Monitor Road as a Township Road and appears to be much the same roadway as when it was initially opened. There appears to have been some minor clearing or trimming of trees over the years, but many of the trees along the roadway have been there for years. As with many county roads,the centerline of the roadway does not follow the section line (therefore the roadway is not centered in the right-of-way.The standards that would apply to any new construction, reconstruction, or 3R work on Monitor Road are included in this study. Horizontal Clear Zone The trees along the roadway are close to the edge of the travelled way and deserve study. If one was to decide what standard should apply to a maintenance project to improve the safety of the roadway,one could consider applying the standards for new construction as far as Horizontal Clear Zone. tatttttttttttttttttt C Ayr itip r &4. 1J c 1 STEVEN rn P.
