The final phase, which began Monday, includes the construction of the south half of the bridge and lanes. As a result, a traffic shift is beginning this week and will be head-to-head in the newly constructed westbound lanes to allow construction to commence in the eastbound lanes.. Rosencutter Road access at Fort Riley Blvd remains closed and detours for south Rosencutter will continue via Seth Child Road and Stagg Hill Road. Poliska Lane and the commercial entrance opposite of Poliska will be right-in, rightout access for the duration of Phase 3.
