. PROPOSED IMPROVEMENTS Hi~hway 96 Imorovements (Ramsev County) The proposed reconstmction of Highway 96 includes a single point diamond interchange between 1-35W and Highway 96. Single point diamond interchanges include a central signalized intersection located in the center of the bridge deck itself to accommodate through traffic on Highway 96 and left-turning traffic from Highway 96 and 1-35W. The interchange design also includes unobstructed right turn ramps to accommodate traffic turning right from both Highway 96 and 1-35W. This type of interchange design provides for high volume of traffic movement cspecially when a large percentage of traffic is turning left to exit or enter the freeway system. The improvements to Highway 96 are currently under design by Ramsey County and are cxpected to be complete within three years. The remainder of Highway 96 is proposed to be reconstructed into a four lane divided highway with turn lanes, shoulders and a raised median throughout similar to the segments nearing completion in Shoreview and Vadnais Heights. Pro\losed Roadwav Imllrovements West Round Lake Road will be realigned through the lndykiewicz property to provide a new intersection with Highway 96 approximately 150 meters (500 feet) east of the current . intersection. The proposed intersection location will provide adequate separation between the proposed interchange with 1-35W and Highway 96. The intersection will initially be constructed as a tee intersection however, as a part of the Highway 96 reconstruction, the entrance to the Arden Manor Mobile Home Park will be relocated to be opposite of West Round Lake Road. West Round Lake Road will be built to MnDOT State Aid Standards. West Round Lake Road is proposed to be a two lane divided bituminous roadway including curb and gutter with a raised median. The Highway 96 approach will include double left turn lanes, one through lane and a right turn lane. The through lane will be closed until the new entrance to the mobile home park is constructed. One 4.8 meter (16 foot) wide southbound lane will be provided along West Round Lake Road. The permanent roadway section will continue from Highway 96 to a point approximately 200 meters (650 feet) south. The last 90 meters (300 feet) of the roadway will be constructed in a temporary condition to allow for matching into the existing 7.2 meter (24 foot) wide roadway. The proposed pavement will be a ten ton design utilizing MnDOT guidelines for flexible bituminous pavements. The pavement cross-section is assumed to include 6 inches of bituminous surfacing placed over 12 inches of class 5 aggregate base. A 12 inch sand subbase with subdrainage pipe will also be constructed to provide for enhanced pavement support, pavement subdrainage and frost protection. A final pavement section will be determined upon the completion of soil borings and analysis of the existing subgrade soils. . 2
