Work crews have been making adjustments today to the warning gates on the Portland side of the Casco Bay Bridge, resulting in several 10-minute closures.

Today’s work will be completed by 3 p.m.

On Tuesday, crews will work on the warning gates in the opposite direction, from South Portland into Portland from 9 a.m. to 3 p.m.

The work will result in multiple 10-minute closures while workers lower the gates to properly align them.
Marine traffic will not be affected.
