Heat likely the cause of Casco Bay Bridge closure Wednesday

PORTLAND PRESS HERALD • June 25, 2025

Northbound traffic into Portland on the Casco Bay Bridge came to a halt Wednesday afternoon as workers addressed a mechanical issue. Heat is the likely culprit for the mechanical issue, which has happened in the past. The police department announced that the northbound lane of the bridge was stuck open in a post on Facebook around 4:10 p.m. The post was updated around 4:30 p.m. to note the bridge was back open.
