Within the metropolitan area, the great majority of principal arterials are under <br /> MnDOT jurisdiction. Principal arterials are typically Interstate highways or other state or <br /> US freeways or expressways. Principal arterials also connect to other cities, regions, and <br /> states outside of the metropolitan area. Principal arterials are intended to maintain average <br /> speeds of 40 mph during peak traffic periods.To maintain mobility and speeds on principal <br /> arterials, land access and transportation system connections are limited. There is little to <br /> no direct land access from principal arterials.Access is limited to interstate freeways,other <br /> Principal Arterials, and A Minor Arterials. Access points are typically grade-separated or <br /> controlled with a signal and are spaced approximately one to two miles apart. Within the <br /> City of Orono, there is one principal arterial: US Highway 12. The TPP does not identify <br /> any specific regional mobility improvements on this highway, although maintenance and <br /> preservation investments will be made on all highways. <br /> City of Orono Community Management Plan 2020-2040 Part 4A, Page 5 <br />
