U.S. Route 30 Business (Portland, Oregon)
From Wikipedia, the free encyclopedia
U.S. Route 30 Business is a 5.56-mile[1] (8.95 km) business route for U.S. Route 30 in eastern Portland, Oregon, running along Burnside Street and Sandy Boulevard. Unlike a standard business route, neither end is at US 30 - the west end is at Route 99E (Martin Luther King Boulevard and Grand Avenue; Pacific Highway East 1E) at the east end of the Burnside Bridge, and the east end is at U.S. Route 30 Bypass (Northeast Portland Highway 123) at the Interstate 205 interchange. It crosses US 30, which is concurrent with Interstate 84, at around its midpoint. The whole route was the Sandy Boulevard Highway - Highway 59 - until July 10, 2003, when it was given to the city (along with an adjacent part of Route 99E/Highway 1E a month later).[2]
Though the west end is just south of an interchange with US 30/I-84, there are no ramps pointing in the correct direction. The reason for this strange end is that US 30 originally exited I-84 there and ran south on Route 99E, and then turned west onto the Burnside Bridge through downtown. (It continued along Burnside Street, 18th Avenue/19th Avenue, Vaughn Street, Wardway Street and St. Helens Road.) When US 30 was realigned to use Interstate 5 and Interstate 405 around the north side of downtown, US 30 Business remained the same (except for a one-block extension west from Route 99E northbound, resulting in a milepost of -0.05 for the west end at Route 99E southbound).
