Update 7:30 a.m. The Ballard Bridge is now open and traffic is running smoothly, but last night around 11:30 p.m. it was closed due to a mechanical problem. We walked up the side of the bridge and spoke briefly to an engineer who said it wasn’t closing all the way down (although it looked down).

Earlier Wednesday afternoon, we saw a couple Twitter messages from people who said the bridge was closed to traffic, but it was apparently able to open by the evening commute. (Thanks Ann for the tip!)
