County Road 101(CR 101) Reconstruction
Virtual Open House
December 2020
CR 101 Project Overview
CR 101 (45th Street SE) from St. Bridgets Road to CR 1, planned for reconstruction in 2021, is a major collector in Olmsted County’s transportation system. This gravel roadway has been a county road since 1969 and has not been reconstructed during the 51 years the County has been responsible for the roadway.
CR 101 Project Need
CR 101 Project Need
Truck traffic is largely prohibited from using the roadway in the Spring.
• The roadway is posted at 6 Tons during the Spring Load Restriction time
period as the gravel roadway does not have adequate strength to carry the
loads during the Spring thaw.
Roadway users experienced a higher crash rate on this gravel surfaced roadway than on similar roadways state-wide for 2017-2019. As traffic continues to increase on the roadway, more users will experience crashes without improvements to the roadway.
Likely contributing factors to the above average crash rate include the type of surfacing and substandard roadway geometrics.
• It is difficult to maintain the gravel surface often enough for the current traffic levels.
• The roadway elevation is nearly the same; or in some cases lower than, the land next to it. This, along with a lack of defined ditches for snow storage and creates snow traps; requiring more frequent winter maintenance.
CR 101 Project Purpose
The reconstruction of CR 101 will result in a roadway that meets current MnDOT State Aid Standards. This will address all existing deficiencies and provide a safer, year-round 10-ton roadway and a multi-use trail.
Design Features • Concrete Pavement
• Bituminous Paved Shoulders
• Bituminous Multi-Use Paved Trail
• ADA Compliant Pedestrian Facilities
• Intersection Lighting
• High Visibility Crosswalk Markings
• Stormwater Treatment
• Roundabout
CR 101 Traffic SafetyCrash Data 2017 -2019 (excludes crashes at intersections)
7 Single Vehicle Runoff the Road Crashes
• 3 involved snowy/icy roadway surface.
• 1 involved a vehicle passing another one and creating a dust cloud. The driver who was passed couldn’t see and ran off road.
• 1 occurred when the roadway was being graded. A car hit the windrow of gravel down the middle of roadway and the driver lost control.
• 1 involved a vehicle that the driver left behind, cause undetermined.
• 1 involved a vehicle pulling a trailer that was avoiding a crash with an approaching vehicle crossing into their lane.

A roundabout is recommended to improve geometrics at the intersection with this project and to set the stage for eliminating substandard horizontal curves in the future.

Insert Layout here, similar to 210th 2nd Open house, allow people to zoom in higher resolution to see details. The county would need to post it on their site so I can link to it.
