The I-5: South Jefferson to U.S. 20 Environmental Assessment project is focused on a six-mile stretch of I-5 in northern Linn County, Oregon between mile post 239 and mile post 233. This section of I-5 serves Millersburg, Albany, and rural Linn County, and currently includes five interchanges: South Jefferson, Viewcrest, Murder Creek, Knox Butte, and US 20. This section of interstate and its interchanges do not function well, which creates vehicle movement conflicts on I-5 and affects access to businesses and homes in the area. These transportation problems are expected to get worse in the future as the region continues to grow.
Actions proposed by ODOT include the following:
· Add an additional travel lane in each direction on the interstate.
· Construction of a new Millersburg interchange at approximately mile point 236.6.
· Removal of the existing Viewcrest and Murder Creek interchanges after completion of the Millersburg interchange.
· Addition of a southbound on-ramp at the Knox Butte interchange.
· Improved connectivity between the Knox Butte and U.S. 20 interchanges.
· Other improvements to interchanges and the local street system to ensure efficient and safe operation of the interchange areas and interstate.
Together these actions are referred to as the “Build Alternative” in the Environmental Assessment. Potential impacts resulting from the Build Alternative are summarized in the Environmental Assessment. When completed, the Environmental Assessment will guide transportation construction in this segment of I-5 over the next 20 years.
Currently this project is in the planning phase and construction funds have not been identified.
