Executive Summary The Anoka County Highway Department has demonstrated dedication and commitment to lead an improvement on TH 47 near the intersection of CR 27 in the City of Ramsey. We have evaluated the safety of several county road intersections along TH 47 and observed that the approach to the CR 27 intersection from the north lacks the appropriate sight distance necessary for safe traffic movement in this area. It has been determined that lowering the profile of TH 47 will drastically improve the safety for traffic negotiating the intersection in question. There has been a significant investment of resources in design, survey, and traffic analysis to develop this cooperative improvement project. We believe that this is an excellent opportunity to partner with Mn/DOT to provide acost-effective solution to the safety problems at TH 47 and CR 27. The proposed TH 47 / CR 27 project includes the following improvements: • Lower the profile of TH 47 approximately 2.50 feet from the intersection of CR 27 north approximately 667 feet. The benefits to TH 47 and CR 27 associated with the above-mentioned improvements include: • Improve sight distance for vehicles traveling south on TH 47 approaching the intersection of CR 27. • Improve sight distance for vehicles turning onto TH 47 from CR 27. • Reduced probability of accidents at this intersection due to insufficient sight distance along TH 47. • Provide safe turning movements for vehicles entering TH 47 from CR 27. • Provide positive guidance and increase public support by improving roadway geometrics on TH 47 and CR 27. • Cost-effective stewardship and management of Mn/DOT and Anoka County Highways. The preliminary cost estimate for the construction of this project $249,322. Anoka County is requesting Mn/DOT pay 100% of the improvements since they are all associated with TH 47. Additionally, 10 percent will be added for engineering and administration creating a total cost of $269,268. This project is a low expenditure solution to a geometrically deficient intersection and is consistent with Mn/DOT and Anoka County safety performance measures. We look forward to a successful submittal in the preservation category of the FY 2010 Cooperative Agreement Program and working collaboratively with Mn/DOT to complete this needed project.
