The Portland Bureau of Transportation (PBOT) is constructing a new active pedestrian and bicycle bridge over I‐405 at NW Flanders Street. The bridge will connect the NW District and the Pearl District with a safer and more comfortable active crossing over I‐405.
What's happening now
Construction begins in July 2020 with some minor traffic impacts including short term parking impacts, tree removal at the east end of the bridge site at NW Flanders and 15th Avenue, and a nighttime closure of the NW Everett Street on-ramp to I-405.
There will be additional street closures in fall 2020, including a full weekend closure of I-405 in this winter in both directions and a five-week closure of the NW Glisan Street off-ramp in August. The news page below will be updated regularly.
Project background and description
Almost since the construction of the I-405 freeway in 1969, the Northwest and Pearl Districts needed a safer connection for pedestrians and people on bikes. The existing crossings over I-405 at NW Everett Street and NW Glisan Street are highly congested at peak hours, do not provide adequate pedestrian and bicycle facilities, and are located in the heart of a busy freeway ramp network.
In 2007, the City of Portland identified NW Flanders St. (and its crossing over I-405) as a biking and walking corridor to serve an area with high potential for future non-motorized trips as well as an alternate seismic-resilient route for emergency vehicles following an earthquake.
