CMP Part 4A. Transportation Plan MINOR ARTERIAL Minor arterials provide supplementary connections between metro centers and regional business concentrations, and more typically in Orono's situation, provide alternative commuter routes to growth centers located west of Orono. Minor arterials are also intended to provide mobility rather than land access, although many of Orono's high-volume minor arterials developed in a manner more typical of collector roads. Minor arterials are divided into two administrative categories. "A" Minor Arterials have a regional significance and are eligible to compete for federal funding, whereas "B" Minor Arterials serve a more local function for shorter trips and are nearly identical in function to Collectors. "A" Minor Arterials are further classified into the following groups: Relievers -Minor arterials that provide direct relief for traffic on major metropolitan highways. These roads typically include the closest parallel routes to the principal arterials. Expanders -Routes which provide a way to make connections between developing areas outside the Interstate (I-494/1-694) ring. County Road 15 is classified as an Expander. Connectors -Roads that would provide good, safe connections among town centers in the urban reserve, urban staging and rural areas. Augmenters -Roads that augment principal arterials within the Interstate (1-494/1694) Ring. County Road 6 east of Highway 12 currently functions as a Reliever for Highway 12, although it would otherwise be characterized as an Expander and a Connector. The Lake Minnetonka Ring Route consisting of segments of both County and City roads would be considered as an expander or connector road functioning to move, principally commuters and some truck traffic, from the western Lake Minnetonka communities into the urbanized areas of the Twin Cities. The Ring Route channels traffic away from Lake Minnetonka to State Highways 12 as well as to County Road 6 which has a direct intersection with Interstate 494 in Plymouth and connections northward to Highway 55. Land use access is intended to be limited to major traffic generators and local street intersections without direct access to individual residences. JURISDICTION: Hennepin County Dept.
