necessitate eliminating the existing intersection and vacating Armstrong between Hwy. 10 and CR 116. Alternative #2 shows Armstrong as it is now, intersecting w/th Hwy. 10. This poses traffic flow problems for traffic coming off the bridge road and heading east on Hwy. t 0. The intersection and its traffic light stops traffic approximately 1/4 mite from the end of the ramp. Traffic coming off.the bridge road as well as traffic already on eastbound Hwy. 10 would be mer~ng and stopping at the same point. Congestion on Hwy. 10 could possib}y 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 frontage/business access road and the residential collector. This would require two bridges. The eastern bridge alignment requires only one overpass. Because this overpass would be close 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 from the river to the Hwy. 10 overpass. EXTRATERRITORIAL ZONING 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. N'W) north of the municipal boundary in Bums Township. Staff researched the options for such ptarming. Minnesota statutes provide for extraterritorial municipal zoning and subdivision authority under certain conditions. A city. may by ordinance e.,aend the application of its zoning regnlations to umncorporamd temtow located within two miles of its limits in any direction, but not in a county, or town which has adopted zoning regulations; ... An), cfi .t3' may thereafter enforce such regulations in the area to the same extent as ff such property were situated within its corporate limits, until the counB' or town board adopts a comprehensive zoning regulation which includes the area. MN Stat 462.357 subd. 1 A municipally, may by ordinance extend the application of its subdivision regulations to unincorporated temtorv located within nvo miles of its limits m any direction, but not in a town wh.ich has adopted zoning regnlations; MN Stat 462.358 subd. la (For these sections, a municipality is defined as any city or town.
