Interstate 5 North - Ashland to Medford

Interstate 5

Interstate 5 enters the Beaver State at Siskiyou Summit south of Ashland. The mountainous stretch in southern Jackson County rises to 4,310 feet above sea level, the highest point anywhere along I-5. The freeway begins a pronounced descent from the summit into the city of Ashland.

Passing along the eastern edges of Ashland between Exits 11 and 19, Interstate 5 continues from short distance to Phoenix and Medford, the Jackson County seat. Once in Medford, the freeway navigates through the heart of the city including an elevated section. West of Central Point, the freeway progresses toward Gold Hill, Rogue River, and Grants Pass.

The city of Phoenix, dubbed "The Other Phoenix" in reference to Phoenix, Arizona, began with the residence of early pioneer Sam Colver in 1851. The Rogue Valley became a gold mining area with the discovery of the Jacksonville gold fields soon thereafter and Phoenix grew as a popular stage stop known as Gasburg around the original Colver House. Growth continued and the establishment of a post office by S.M. Waite introduced the name Phoenix for the town. Waite had a policy with the Phoenix Fire Insurance Company and decided to name his post office Phoenix. The name eventually stuck.

Medford began as an early 1880s railroad town built by the Oregon & California Railroad at a site along Bear Creek. Originally dubbed Middle Ford, railroad engineer David Loring shortened the name to Medford based upon his home town of Medford, Massachusetts. The O & C Railroad reached the settlement by 1884, and incorporation of the town occurred on February 24, 1885. Medford's growth continued as a agricultural and timber center and the seat of Jackson County. The largest city in southern Oregon operates as a regional trade center today.
