A right-in/out access may be required for safety and traffic flow purposes if other access options are not consistent with public safety and traffic flow. Access Design Criteria Table 2 provides design criteria for private access onto <Insert Agency>’s roadway, including width, grade, landing size, and side slopes.

(b) The closest access point to an intersection may need to be outside the functional area of that intersection depending on the local geometric and traffic characteristics of the county roadways. Functional areas of an intersection may be up to 820 feet. (c)Minimum radius dependant on angle of driveway approach; see MnDOT’s Road Design Manual. (d) Entrance surface out to culvert or ditch line shall have a minimum drop of 6 inches at 20 feet from the edge of the driving lane. Maximum elevation drop is 15 inches at 20 feet from the edge of the driving lane. (e) New side slopes of 1:6 are required when other approaches on the roadway are 1:6.
