Access to the southwest quadrant will be served by a future roadway which will connect 21st Avenue to CSAH 14 at a new location. The new roadway will connect with CSAH 14 opposite the ramp in the northwest quadrant. (This future access road is not included in the construction or right of way costs for the interchange Project.). Access to all businesses will be maintained throughout the project construction phase. The proposed new bridge will follow urban design standards and be 250 feet long with a 6 foot median. Westbound, there will be 8 foot and 4 foot shoulders, two 12 foot through lanes, and a 12 foot right -turn lane. Eastbound, there will be a 14 foot left-turn lane, two 12 foot through lanes, an 8 foot shoulder, and a 10 foot pedestrian /bicycle trail. A 10 -foot wide bituminous trail will be constructed along the south side of CSAH 14 providing an ultimate link between the regional park to the west and the rush line corridor to the east in the City of Hugo. Cross walk striping and signing will be included at both ramp intersections as well as other local road connections. The project is proposed to be constructed over two phases. During the first season, the north half of CSAH 14 as well as the ramps and loops will be constructed while traffic remains on the current roadway. The north half of the new bridge can be constructed during the first season. During the second season of construction, traffic will be switched to the new pavement and bridge while the south half of CSAH 14 and the bridge are completed. The construction plan set lays out a detailed sequence of stages and temporary connections to provide a reasonable and safe method to construct the new interchange while maintaining traffic and access to motorists. IV. Roadway improvements a. Roadway Improvements: The Roadway improvements were developed as part of the Geometric Layout which was reviewed by several agencies and ultimately Staff Approved by Mn /DOT on October 2, 2008. Roadway improvements include increased capacity and access management along CSAH 14. Improved intersection operations are also expected. See Figure 3.
