Interstate 5 North - Kalama to Castle Rock

Interstate 5

Longview is the first city of significant size along Interstate 5 north beyond Vancouver. Longview was platted in 1921 and the Long-Bell Logging company purchased the site and planned the entire city before construction even began (City of Longview, n.d.).

One of western Washington's older communities, Castle Rock was incorporated in 1890 and its name derives from a 190-foot high volcanic formation located at the heart of town.
