Flanders Crossing is a new active pedestrian and bicycle bridge planned for over I‐405 at NW Flanders Street in Portland. The bridge is required to provide the residents of the NW District and the Pearl District a safer active crossing over I‐405.
Almost since the construction of the I-405 freeway in 1969, a safer connection for pedestrians and bicyclists from NW District to Pearl District was warranted. The existing crossings over I-405 at NW Everett St. and NW Glisan St. 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 the NW Flanders St. (and its crossing over I-405) as a bike 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. The project is now envisioned as a neighborhood greenway that will extend on Flanders St. from NW 24th Ave. to Naito Parkway. The Feasibility Study & Bridge Alternatives Analysis focuses solely on the crossing of NW Flanders at I-405.
