35 LOCAL STATE-AID ROUTE STANDARDS,FINANCING 8820.9941 One-way streets must have at least two through-traffic lanes. When a median is included in the design of the two-way roadway,a one-foot reaction distance to the median is required on either side of the median. Minimum median width is four feet. Urban design roadways must be a minimum nine tons structural axle load design. Roadways not on the state-aid system are not subject to the minimum structural design strength requirements. The minimum curb-to-curb width of a new bridge must be the required street width,but in no case less than required per Minnesota Statutes, section 165.04. HS 25 loading with AASHTO Standard Specifications or HL-93 loading with load and resistance factor design (LRFD) is required for new or reconstructed bridges and a minimum of HS 18 loading is required for all rehabilitated bridges. Where the new bridge approach roadway includes elements for the accommodation of pedestrians or bicycles,the new bridge width must also provide for pedestrians or bicycles unless pedestrians or bicycles are otherwise accommo- dated. For ADT less than 150,the widths of bridges to remain must be at least the sum of the lanes. For ADT greater than or equal to 150, the widths of bridges to remain must be at least the sum of the lanes plus half the sum of the shoulders,parking lane,and curb reaction distance. Clearance of 1.5 feet from the face of the curb to fixed objects must be provided when the posted speed is 40 to 45 mph. A ten-foot clear zone measured from the driving lane must be provided when the posted speed exceeds 45 mph. For volumes greater than 15,000 projected ADT,at least four through-traffic lanes are required,unless a capacity analysis demonstrates that a different lane configuration achieves level of service D or better.

The bicycle facility design standard in this part applies when the road authority has determined that the roadway will be specifically designed to include an on-road bicycle facility and only if the roadway surface is paved.
