Duplainville Road is in poor condition and is in the City's plan to complete a reconstruction in 2022. As such, Staff has begun the design of the roadway. Given the local arterial status of this roadway and the trucking that occurs along the corridor, Staff hired a consultant to review a few alternatives for the road section and composition. See the attached Alternative Analysis. The first alternative included asphalt as the surface for the entire length of the roadway for an estimated cost of $5,688.500. The second alternative included concrete as the surface for the entire length of the roadway for an estimated cost of $7,188,500. The third alternative included asphalt north of Capital Drive and concrete south of Capital Drive for an estimated cost of $6,188,500. The third alternative was reviewed as the truck turning movements caused by the Quad Graphics operations take place south of Capital Drive and have a large impact on the roadway.  While north of Capital Drive, it is mainly a through trucking route which has less impact on the roadway. In general, a concrete roadway will hold up better when there are large amounts of truck turning movements. In addition, concrete generally has a longer life than asphalt pavements. However, we have not completed a full life cycle cost to compare these types of payments at this time.  Staff would like to recommend pursuing the concrete roadway and complete the life cycle cost analysis to confirm this is the best decision long term for the City.  The Public Works Committee prefers the Alternate 3 which is the concrete south of Capitol Drive and asphalt north of Capitol Drive.

As part of the road reconstruction, the City has authorized designing a trail system along Duplainville Road in conformance with the Bike & Pedestrian Plan. The Bike and Pedestrian Committee recommended an off trail system preferably on the west side of Duplainville Road. However, topography and existing impediments indicate the east side is a more economical location. Therefore, a 10' wide bike/pedestrian path is planned for the east side. The estimated cost for this trail is $361,500 when completed as part of the road project. Just recently, the Common Council authorized the design of the trail along Lindsay Road from Duplainville Road to the Pewaukee Sports Complex to be completed as part of this project. The Bike and Pedestrian Committee also recommended an off road system on the north side of Lindsay Road at an estimated cost of $300,000. The Lindsay Road trail has multiple environmental concerns (wetland, floodplain, and creek crossing) which increases the cost of the trail.  The above costs do not include any land acquisition costs which will likely be required from 10 properties to accommodate the bike/pedestrian path on Duplainville Road and is not yet known if any are required for Lindsay Road. This is being further analyzed to determine the final impacts, but the Duplainville Road road section needs to be decided first.
