I-5: Medford Viaduct Environmental Study

Planning Phase

Region 3: Southwestern Oregon (Medford, Jackson)

​​​​​​This study examines safety, operational and structural needs of the Interstate 5 Medford Viaduct and sets the course for future widening and strengthening of the 3,200-foot structure.​

Details

About

​This is a planning study for the Interstate 5 viaduct that runs through Medford. The study will develop a priority list of specific improvement projects for the viaduct, focusing on capacity, safety, and changes to the local road network.

Location

I-5 | ​Medford

Cost and Funding

No funding has been identified for either design or construction.

Construction is estimated at more than $80 million.

Benefits

​The Medford Viaduct was constructed in 1962, when traffic volumes were much lower than today. This study will lay the groundwork for the widening of the viaduct (for shoulders and a third lane) and seismically strengthening it. These changes will make the viaduct safer for motorists and extend its useful life.

The study has six primary objectives:
  • Protect the viaduct’s function;
  • Develop concepts to improve safety and maximize operational efficiency;
  • Evaluate the need for capacity improvements to address future needs based on the adopted comprehensive land use plans of Medford and Jackson County;
  • Identify potential local system enhancements that maintain connectivity and complement the viaduct’s function;
  • Coordinate the study’s efforts with other plans and projects in the study area; and
  • Prioritize viaduct improvements with consideration for potential funding mechanisms.
