OregonRoute 99E is an Oregon state highway that runs between Junction City, Oregon and an interchange with I-5 just south of the Oregon/Washington border, in Portland. It, along with OR 99W, makes up a split of OR 99 in the northern part of the state. This split existed when the route was U.S. Route 99, when the two branches were U.S. 99W and U.S. 99E. Currently, OR 99E and OR 99W do not reconvene at a northern junction in Oregon; OR 99W has been truncated from its original route, and ends in Downtown Portland, several miles south of its original northern terminus; nor is OR 99 signed anywhere in Portland.
History
Route description
OR 99E has its southern terminus in Junction City. Almost immediately after leaving the city limits the route crosses the Willamette River, and serves Willamette Valley towns such as Harrisburg and Tangent. North of Tangent, the route enters the city of Albany and serves as a main thoroughfare through town. At the northern end of Albany, OR 99E joins I-5. OR 99E remains co-signed with I-5 until Salem where it again splits off from the interstate, serving many towns in northern Marion County. . North of Salem, OR 99E serves the northern Willamette Valley, passing through cities such as Woodburn, Hubbard, and Canby, before entering the Portland metro area in Oregon City. The stretch between Canby and Oregon City is notorious for frequent and serious accidents. Starting in Oregon City, and continuing through the suburban communities of Gladstone, Oak Grove and Milwaukie, OR 99E is known as McLoughlin Boulevard. The road crosses the John McLoughlin Bridge just south of Gladstone. North of Milwaukie, OR 99E is a high-capacity urban expressway. In Portland, OR 99E continues as the McLoughlin Boulevard expressway until passing beneath the Ross Island Bridge, where it runs on the couplet of Martin Luther King Jr. Boulevard and Grand Avenue. It is the main north-south arterial through the central east side of the city. North of NE Broadway, OR 99E continues as MLK Jr. Boulevard and passes through several Northeast Portland Neighborhoods until its terminus at an interchange with I-5 and OR 120 in Delta Park, just south of the Columbia River crossing. .
