Page 2 of 3 Project Purpose The purpose of the TH 169 reconstruction project is to improve vehicle safety and mobility along the TH 169 corridor between the Mississippi River and 197th Avenue, in Elk River. The project received Corridors of Commerce funding in 2018 to convert TH 169 to a freeway section through Elk River. Pedestrian safety and mobility will also be increased with the project. Project Description The TH 169 reconstruction project stretches approximately five miles along TH 169 from the Mississippi River at the South to the intersection with 197th Avenue at the North. The proposed project will eliminate five existing signal systems along TH 169 through revisions to the TH 10/TH 101/TH 169 system interchange and by adding four new grade separated interchanges at cross streets through Elk River. TH 169 will be reconstructed as an urban highway with median barrier separation and curb & gutter along the outsides. Auxiliary lanes will also be added between several interchanges to accommodate traffic demand. Five new bridges will be constructed with the project along with new trail and walk connections throughout the corridor. Planned Project Schedule Final design work for the TH 169 project is anticipated to begin summer of 2020. Construction will begin following a summer 2022 letting and last through the 2024 construction season. A minimum of a single thru lane of traffic will be maintained along TH 169 throughout construction. A minimum of two intersection access points will be maintained to and from TH 169 in Elk River throughout construction. Temporary bypasses, weekend closures, and detour routes are anticipated to facilitate construction. City's Estimated Project Costs Some project costs are the City's responsibility, as detailed in MnDOT's cost participation policy. (See the policy and the Cost Participation and Maintenance with Local Units of Government Manual at MnDOT's this website: http://www.dot.state.mn.us/policy/financial/fmO11.html). Total project costs for S.P. 7106-87 are estimated to be approximately $160 million. Based on the staff approved layout, the City of Elk River's cost participation is estimated to be approximately $3 million. Attached is MnDOT's current estimate of the City's costs for S.P. 7106-87. Please note that the estimated costs represent a good faith cost estimate based on preliminary design work. Costs will be refined and further validated as final design progresses.
