Centerville 2040 Chapter 6: Transportation <br /> During peak traffic, minor arterials in developing areas are intended to <br /> maintain 30 mph average speeds. As a result, transportation system <br /> connections are limited to interstate freeways, other principal arterials, other <br /> minor arterials, collectors, and some local streets. Land access is limited to <br /> concentrations of commercial and industrial land uses. The Metropolitan <br /> Council has established a system of "A" Minor and "B" Minor arterials. "A" <br /> Minor arterials are eligible for federal funding administered by the <br /> Metropolitan Council. <br /> The Metropolitan Council has further split "A" Minor arterials into four types, <br /> described below: <br /> • Relievers: Arterials located parallel to congested principal arterials. The <br /> purpose of "A" Minor Relievers is to provide additional capacity in <br /> congested corridors. <br /> • Augmenters: Arterials that supplement the principal arterials system <br /> within urban centers and urban communities. <br /> • Expanders: Arterials that supplement principal arterials in less-densely <br /> developed areas of the metro area. <br /> • Connectors: Arterials that provide connections between rural towns <br /> and connect rural areas with the principal arterial system. <br /> A Functional Classification Map of the City's Road and Highway System is <br /> included as Map 6-1. Interstate 35E (a principal arterial) is located just east of <br /> the City limits. A full interchange with Anoka County State Aid Highway 14 <br /> (CSAH 14) provides interstate access to the City. <br /> Running east-west through the downtown area, CSAH 14 is the City's most <br /> used "A-Minor Arterial". The A-minor designation is further defined for this <br /> roadway as an "Expander". CSAH 14 is currently and planned to remain a <br /> three-lane roadway. The city's only other A-minor arterial is CSAH 54 which is <br /> currently and planned to remain a two-lane roadway running north-south <br /> along the City's eastern edge. It is considered an A-minor Reliever for its role <br /> as a frontage road to 35E. Both A-minor arterials are under county <br /> jurisdiction. The county also has a B-minor Arterial; CSAH 21 running north- <br /> south along the City's western edge and leading into the downtown where it <br /> terminates at CSAH 14. <br /> Chapter 6 I Page 4 <br /> 36 <br />
