HIGHWAY 10 CORRIDOR STUDY - FINAL REPORT <br />Existing Conditions Summary <br />Highway 10 is an important corridor for personal and freight transportation, connecting local and <br />regional users to greater Minnesota. After analysis of the current conditions along the roadway, the <br />following concerns were identified: <br />• All study intersections currently operate at an overall LOS C or better. <br />• Sides -street access to Highway 10 is challenging, with most stop - <br />controlled approaches operating at LOS E or worse during the peak <br />periods. <br />OPERATIONS • Existing ADT volumes on Highway 10 are approaching the facility's <br />planning -level capacity. <br />• There are limited or no adequate gaps for motorists to safely access <br />Highway 10 during the peak periods. <br />• Vehicles were observed using the shoulders as acceleration lanes to <br />access Highway 10. <br />• 200 crashes have occurred within the study area during the past <br />5-years. <br />• The study corridor has crash and severity rates that are statistically <br />significant compared to locations with similar characteristics. <br />• The 171st Avenue intersection has crash and severity rates that are <br />statistically significant compared to locations with similar <br />SAFETY characteristics. <br />• The Intersections of 173rd Avenue and 165th Avenue had crash rates <br />just under the statewide expected crash rate. <br />• Majority of the crashes occurred at intersections <br />(61 percent) and were mostly rear end and angle crash types. Majority <br />of the rear end crashes were for westbound vehicles at the signalized <br />intersection of 171st Avenue. <br />ACCESS <br />• Current access along Highway 10 does not meet the MnDOT guidelines <br />for access spacing. <br />• Most land adjacent to Highway 10 is agricultural and impacts on this <br />land should be minimized. <br />SOCIAL, <br />• Several water resources are in the study area. Future <br />ENVIRONMENTAL, <br />recommendations should minimize impacts to floodplains, wetlands, or <br />AND ECONOMIC <br />drinking water supply management areas. <br />CONTEXT <br />• The roadway is close to many potentially contaminated sites and must <br />minimize interaction with these sites. <br />• The Oliver Kelley Farm, a nationally registered historic property, is <br />located directly adjacent to the corridor. <br />a GHW4�, <br />■ _ <br />�RRIOORSN� <br />
