Harbor Drive

Harbor Drive is a short roadway in Portland, Oregon, spanning a total length of 0.7 miles (1.1 km), which primarily functions as a ramp to and from Interstate 5. It was once much longer, running along the western edge of the Willamette River in the downtown area. Originally constructed from 1942–43, the vast majority of the road was replaced with Tom McCall Waterfront Park in the 1970s. Signed as U.S. Route 99W, it had been the major route through the city and its removal is often cited as the first instance of freeway removal in the U.S. and as a milestone in urban planning; the original road is remembered as the first limited-access highway built in the city.
