Pacific Highway is the name of some highways in the US. It is most commonly used to refer to US Highway 101 in Oregon, as that is where it most closely follows the coastline. Parts of Highway 101 in Washington are also known as Pacific Highway. However, large stretches of Washington State Route 99 were also named Pacific Highway, although some of it has been renamed International Boulevard. In California, the northern part of Highway 101 can be called Pacific Highway, but, south of Eureka, California, California State Route 1 is closer to the coast, and is more often referred to as Pacific Coast Highway.
