I I. Introduction As ordered by the Lino Lakes City Council on April 27, 2009, a Feasibility Study has been prepared for State Project (SP) 02- 614 -28, CSAH 14 & I -35E interchange project. The proposed project consists of total reconstruction of the existing interchange which is located at the intersection of Interstate 35E (I -35E) and County State Aid Highway (CSAH) 14 in Anoka County. The project also includes the widening of CSAH 14 from two lanes to four and six lanes as well as replacement of the existing CSAH 14 bridge over I -35E, Bridge #020803. See Figure 1 for project location. The proposed reconstruction of the CSAH 14 & I -35E interchange is a subsequent phase of the proposed improvements along CSAH 14. Anoka County is currently upgrading CSAH 14 to a four lane divided facility from I -35W to CSAH 54. Washington County recently upgraded CSAH 14 /CSAH 8 to a four lane divided facility from just east of I -35E to TH 61. The CSAH 14 & I -35E interchange will provide the needed link and complete the improvements in this area. The purpose of this report is to document the improvements as well as the estimated costs proposed under this project and provide a recommendation regarding the feasibility of the project to move forward and be partially funded by the City of Lino Lakes and its property assessments. Appendix A contains a detailed summary of the Feasibility Study process timeline. II.
