Please note that the East Haddam Swing Bridge is undergoing a major multi-year renovation (see the link for schedules and webcam links). The bridge closure schedule outlines days the bridge is scheduled to be completely closed. Alternatives are the bridges through Middletown or Old Saybrook, and the seasonal Chester-Hadlyme ferry.
