necessitate eliminating the existing intersection and vacating Armstrong between Hwy. 10 and CR 116. Alternative #2 shows Armstrong as it is now, intersecting with Hwy. 10. This poses traffic flow problems for traffic coming offthe bridge road and heading east on Hwy. 10. The intersection and its traffic light stops tr~c approximately 1/4 mile fi.om the end of the ramp. Traffic coming offthe bridge road as well as traffic already on eastbound Hwy. 10 would be merging and stopping at the same point. Congestion on Hwy. 10 could possibly be made worse rather than alleviated. Since relieving congestion on the highway is a primary goal of constructing a river bridge, the western bridge alignment need to be considered carefully. Another difficulty is that the western alignment means the bridge road travels over more land and over two proposed roads--the highway frontageTbusiness access road and the residential collector. This would require two bridges. The eastern bridge alignment requires only one overpass. Because this overpass would be ciose to the highway overpass, there would be less need for grade changes of the bridge road. The western bridge alignments, in contrast, would require either two overpasses in addition to the highway overpass or would require that the entire bridge road be elevated for its entire length--approximately 3/4 mile. The road from the eastern bridge alignment would be less than 1/2 mile long fi.om the river to the Hwy. 10 overpass. EXTRATERRITORIAL ZOI~q]~G Regarding the traffic through the northern parts of the city, the Commission discussed the possibility of planning for the area along Co. Rd. 83 (Armstrong Blvd. NW) north of the municipal boundary in Burns Township. Staff researched the options for such planning. Minnesota statutes provide for extraterritorial municipal zoning and subdivision authority under certain conditions. A city may by ordinance extend the application of its zoning regulations to unincorporated territory, located within two miles of its limits in may direction, but not in a county or town which has adopted zoning regulations; ... Any city may thereafter enforce such regulations in the area to the same extent as if such property were situated within its corporate limits, until the county or to~vn board adopts a comprehensive zoning regulation which includes the area.
