List of unused highways in Oregon

An unused highway may reference a highway or highway ramp that was partially or fully constructed but was unused or later closed. An unused ramp can be referred to as a stub ramp, stub street, stub-out, or simply stub. The following is a list:

Oregon

Portland

• Just before the northeast end of the Marquam Bridge are two stubs for the cancelled Mt. Hood Freeway. Additional ramp stubs to this cancelled freeway were removed when Interstate 5 (which runs on the Marquam Bridge) was widened. 19

• On the Grand Avenue Viaduct (Oregon Route 99E) is a ramp stub that was to connect to the Mt. Hood Freeway. Viewable here. A construction project is underway to replace this viaduct; this project will likely involve removal of any ramp stubs.

• The western end of the Hawthorne Bridge used to connect to the Harbor Drive freeway, which has been torn down. A former cloverleaf ramp in the northeast quadrant (seen in operation here) is now a stub ramp. Also visible is another ramp connecting the bridge to Naito Parkway and is now used as a pedestrian and bike path connecting the bridge to Tom McCall Waterfront Park. 20

• The Front Avenue overpass over Interstate 405 is wider than it needs to be. Back when U.S. Route 26 was routed north of its current alignment, it was signed on this bridge until 1957. It was here that ramps allowed access to Harbor Drive. 21

• On the west end of the Steel Bridge was a ramp that connected southbound Oregon State Route 99W traffic from the bridge to NW 1st Avenue. When Metropolitan Area Express (MAX) Light Rail was added to the bridge between 1984 and 1986, this ramp was closed to traffic and used exclusively for both directions of MAX trains. The ramp as a road is shown on this map. One can also see the rail lines on the bridge here 22

• On the ramp from I-5 southbound to I-84 eastbound, and on the approach from I-84 west to I-5. These may have been intended to connect I-84 with the Steel Bridge. 23

• On the I-5 ramps to and from the northern end of I-405, for the proposed Rose City Freeway through northeast Portland. A half-built stack interchange was built, including a portion of freeway structure past I-5 from the Fremont Bridge. The freeway structure was eventually reconfigured to connect to N Kerby Avenue at the request of nearby Emanual Hospital. Ramps connecting the Kerby Avenue connector to I-5 were left incomplete. 24

• The massive I-405/US 30 interchange at the west end of the Fremont Bridge was built for the cancelled I-505 project. Initially, this sat as a ramp stub until a temporary connection to NW Vaughn Street was built. The Vaughn Street connection was reconfigured into a short stretch of freeway rerouting US 30 onto a new 4-lane undivided highway called Yeon Avenue. Two ramp stubs exist just short of Vaughn Street that may have provided the temporary connection. 25

• Over the access road to the Sunset Transit Center in Beaverton is an overpass whose only purpose is to connect future parking structures in a later, as yet unplanned expansion. The overpass itself is paved; neither approach is at this time. It can be viewed at 26. (What appears to be a ramp stub leaving U.S. Highway 26 westbound immediately south has since been completed, and is now part of the alignment for the recently-reconfigured onramp from Oregon State Route 217 northbound to US 26).

• Along I-205, between the interchange with I-84 and the Holgate Boulevard overpass, are a series of what appear to be ramp stubs (including a tunnel under the freeway). In reality, this is a right-of-way which was reserved for light rail, and will be the route of the planned MAX Green Line in the near future. 27 28

• As an example of a recently-built ramp stub; in 2000 the interchange between Oregon State Route 217 and Interstate 5 in Tigard was redesigned. The project was planned in two phases; only phase 1--construction of a flyover ramp from I-5 NB to 217 NB, redesign of the other ramps, and several other improvements--was completed. Phase 2 is currently unfunded, has no timetable for construction, and is unlikely to be completed in the foreseeable future due to lack of funding. A ramp stub, located on the ramp from SB OR-217 to SB I-5, was included in phase 1. 29

Eugene

• From Interstate 105 eastbound (though heading north), just after the 1st Avenue overcrossing (and just before crossing the Willamette River), for a planned interchange with the now-cancelled Roosevelt Freeway 30
