Portland's Steel Bridge was closed for more than an hour Tuesday afternoon after a suspicious box was found on a bridge railing.
Several calls were made to 911 about a bicyclist who left a tool box on the Steel Bridge Tuesday afternoon.
Portland Police officers found the box and closed the bridge until it could be checked out by the Metropolitan Explosives Disposal Unit.
Closure of the bridge affected afternoon commute traffic, TriMet buses and MAX trains. MAX passengers had to use shuttle buses to get around the closure.
The bomb squad determined the box did not contain explosives. It was a tool box that fell off of a TriMet maintenance vehicle. The cyclist picked it up in the road and placed it on the railing.
Portland Police say it's appropriate to report suspicious devices, because it's better to be safe and have them checked out.
