The Sarah Mildred Long Bridge will be closed for an undetermined amount of time after it became stuck about a foot above its normal resting place.
According to the Department of Transportation, crews were doing a "cold weather lift." No ship was passing under it, but workers were lifting the span to keep it from freezing.
As the bridge was being lowered, it became lodged about a foot off the normal roadway. Workers discovered some damage to the track, and the DOT said it wasn't sure how long it would take to fix.
Officials asked drivers to avoid the area.
