8820.9926 LOCAL STATE-AID ROUTE STANDARDS,FINANCING 34 pedestrian traffic,on-street parking,intersection and driveway spacing,rights-of-way con- straints,vehicle turn lane configuration,sight distance,sight lines,bus routes,other nonmo- torized uses,functional classification,or other factors. Dimensions less than those indicated in the chart require a variance in accordance with parts 8820.3300 and 8820.3400. Widths of bridges to remain in place must equal roadway pavement width. Bridges narrower than these widths may remain in place provided that the bridge does not qualify for federal-aid bridge funds. H 15 inventory rating is required. Any highway that was previously built to state-aid or state standards,that was granted a variance to standards in effect at the time of construction or reconstruction, or that is a trunk highway turnback,may be reconditioned. The proposed structural design strength must accommodate a minimum of seven tons per axle. Subp. 2. [Repealed, 23 SR 1455] Statutory Authority: MS s 14.386,• 162.02; 162.09 History: 20 SR 1041; 23 SR 1455; 24 SR 1885; 29 SR 449; 37 SR 697 8820.9936 MINIMUM DESIGN STANDARDS, URBAN; NEW OR RECONSTRUCTION PROJECTS. New or reconstruction projects for urban roadways must meet or exceed the minimum dimensions indicated in the following design chart.

Factors to consider include safety,speed,popu- lation/land use,benefit/cost analysis,traffic mix,peak hourly traffic,farm equipment,envi- ronmental impacts,terrain limitations,bicycle traffic,pedestrian traffic,other nonmotorized uses,functional classification,or other factors. Widths less than those indicated in the chart require a variance in accordance with parts 8820.3300 and 8820.3400. (a) One-way turn lanes must be at least ten feet wide,except 11 feet is required if the design speed is over 40 mph. (b)Wherever possible,lane widths of 12 feet,rather than 11 feet,should be used. (c)May be reduced to two feet if there are four or more traffic lanes and on one-way streets. (d)No parking is allowed for six or more traffic lanes or when the posted speed limit exceeds 45 mph. (e)Curb reaction must be provided only where parking is not provided.
