Transportation
Engineering And Design
The Portland Bureau of Transportation (PBOT) is constructing a new earthquake-ready bridge to provide better access for freight, pedestrians, and people biking. Bridge will fill the gap between the Holman Neighborhood Greenway and the NE 47th Avenue protected bikeway.

The current bridge over NE Lombard Street is on a recommended Emergency Transportation Route but is vulnerable to earthquakes. Freight uses the bridge as a connection between NE Lombard Street and Columbia Boulevard, but the current bridge's height and weight restrictions limit freight transportation. In addition, the current bridge does not have enough room for pedestrians and people biking. This new connection would fill the gap between the Holman Neighborhood Greenway and the protected bikeway on NE 47th Avenue. When it's complete, the bridge will provide better access for freight, pedestrians, and people biking. 

Rendering A shows how the new bridge will look approaching from the north: a 6-foot wide buffered bike lane to the left, a 13-foot wide traffic lane in each direction, and a 10-foot wide multiuse path to the right.

Rendering B shows a cross-section of the bridge itself, with a 7-foot wide elevated bike lane on the left, 13-foot wide traffic lane in both directions, and a 10-foot wide multiuse path on the right side of the bridge.

Rendering C shows how the new bridge will look approaching it from the south: a 7-foot wide bike lane to the left, with a 3-foot buffer, a 13-foot wide traffic lane in each direction, and a 12-foot wide multiuse path to the right.
