Crews have opened two travel lanes on Portland’s North Going Sreet bridge after a train crashed into the bridge’s support beams Saturday morning. One lane in each direction is open on the north side of the bridge. The bridge normally has three lanes running in each direction. A path for bikes and pedestrians is also open.

The bridge provides the only street access to Swan Island, an industrial area employing hundreds of workers. The Portland Bureau of Transportation warned commuters of congestion and travel delays.

The bureau said there’s no timeline for when the bridge’s remaining lanes will reopen. That depends on how long it takes to repair the bridge’s concrete support columns. Engineers are continuing to assess the damage caused when a Union Pacific train derailed Saturday and crashed into the columns.
