CONCEPTS CONSIDERED Highway 13 at CSAH 101 in Savage, MN parcels have already been purchased using RALF money. This land could be utilized for storm water ponding to free up space for development in The COR area. 4. Realign Highway 10 Between Ramsey and Sunfish Lake Blvds and Construct North Frontage Rd - Project 3-1-4 The remaining private accesses onto Highway 10 within Subarea 3 are along the north side in-between Ramsey Blvd. and Sunfish Lake Blvd.. Of the 14 existing accesses along the highway, five would be closed and the remaining could be relocated to a new frontage road. In order to fit a frontage road along this stretch without requiring a significant amount of right-of-way, westbound Highway 10 would need to be shifted south. This shift will accommodate the frontage road within existing MnDOT right-of-way but would still provide enough separation between eastbound and westbound Highway 10. Due to the proximity of the frontage road to the westbound mainline, a median barrier would be used. The westbound left turn could remain onto Feldspar St. by constructing a channelized left turn lane. This concept could tie into the frontage road project identified in Subarea 4, which would complete a local road network along the north side of the highway from Ramsey Blvd. to Sunfish Lake Blvd. Approach 2 and 3 There are multiple concepts to attain continuous flow for eastbound and westbound traffic through this subarea including: 1. High T at Ramsey Blvd. with Local Street Overpass - Projects 3-2-1 and 3-2-2a This concept would create a High T intersection at Ramsey Blvd. as well as a local street overpass to serve the north/south through traffic. The High T would be similar to the Highway 13/101 interchange in Savage, MN (see photo) but would incorporate a fourth leg on the south side as a right-in/right- out. Both directions of mainline through traffic would be uncontrolled at this location with westbound going over on a bridge. The eastbound and south - bound left turns would remain signalized at -grade. Another option would be to build the westbound flyover only and keep the eastbound signalized. This would maintain crossing movements. The local street overpass at Rhinestone St. would connect The COR to the south side of Highway 10, in- cluding the regional park. However, the City of Ramsey expressed concerns about this overpass as it could prevent development from occurring on the south side of the highway. For this reason, Rhinestone St. over- pass was officially removed from further consideration. This project could be constructed without the local overpass; however, north and south through traffic as well as westbound and northbound left turns would not be served at this location. 2. Eastbound and Westbound Flyovers - Projects 3-2-1 and 3-2-2b The final build -out for this concept could include flyovers for both eastbound and westbound traffic along with on and off ramps. Unlike the previous concept, this idea would provide full access at Ramsey Blvd. without needing additional structures or projects elsewhere. The flyovers could be constructed in stages like the previous concept. The westbound flyover could be HIGHWAY 10 ACCESS PLANNING STUDY 52
