Oregon Route 99E (OR 99E) is a north‑south state highway in the U.S. state of Oregon. The route follows the historic alignment of U.S. Route 99E, a former split of the trans‑continental U.S. 99, and serves as a parallel arterial to Interstate 5 (I‑5) on the east side of the Willamette River between the Portland metropolitan area and the community of Junction City. The highway is maintained by the Oregon Department of Transportation (ODOT).
Route description
- Southern terminus: Near Junction City, OR 99E begins at an interchange with I‑5 (Exit 149).
- Northern terminus: In Portland, the route ends at an interchange with I‑5 (near the Marquam Bridge, Exit 2).
Between these points, OR 99E traverses a corridor of approximately 119 mi (191 km). The highway passes through a series of urban and rural communities, including:
- Woodburn – intersecting Oregon Route 214.
- Gresham – intersecting U.S. Route 26 (Mount Hood Highway).
- Gladstone – providing access to local streets and the Willamette River waterfront.
- Portland – crossing several major north‑south streets and providing connections to I‑5, I‑84, and other state routes.
The route generally parallels I‑5, often serving as an alternate local thoroughfare for traffic between the same regional centers. In the Portland area, OR 99E runs along portions of the historic “East Bank” streets, including a segment known locally as “East Burnside Street.”
Historical background
- U.S. Route 99E (1926–1964): The alignment that now carries OR 99E was originally designated U.S. Route 99E, one of two branches (the other being U.S. Route 99W) of the historic U.S. 99 that split in the Portland area.
- State designation (1964): Following the decommissioning of U.S. Route 99 in Oregon in 1964, the former U.S. 99E alignment was renumbered as Oregon Route 99E.
- Subsequent changes: Minor realignments have occurred over the decades, primarily to accommodate the construction of I‑5 and related interchanges. The route has remained largely unchanged in its overall north‑south orientation.

Function and significance
OR 99E provides an important local and regional link for commuters, commercial traffic, and freight movement between the Portland metropolitan area and the smaller communities of the Willamette Valley. It also serves as a secondary route for travelers seeking alternatives to the limited‑access I‑5, particularly for access to downtown Portland and adjacent neighborhoods.
Maintenance and signage
The highway is signed with the standard Oregon state route shield (black numerals “99E” on a white background) and is subject to ODOT’s routine maintenance programs, including resurfacing, snow removal, and safety improvements.
