Coast Guard announces Piscataqua River closure near Sarah Mildred Long Bridge

BOSTON — The Piscataqua River, in the vicinity of the Sarah Mildred Long Bridge in Portsmouth, New Hampshire, will be closed to all marine traffic for a 10-day period from 6 a.m. on Oct. 17, 2017 to approximately 6 a.m. on Oct. 27, 2017.

The river closure will enable Maine Department of Transportation (ME DOT) and Cianbro Construction to install the new lift span across the main shipping channel and is necessary to provide for the safety of all waterway users and construction workers during the operation.

The Coast Guard has attended multiple stakeholder meetings hosted by ME-DOT where commercial users of the river have been notified of the upcoming closure. Additionally, the Coast Guard will announce the closure with a Broadcast Notice to Mariners and will also conduct direct outreach to the recreational and commercial waterway users in the area. The waterway closure dates will also be published in the weekly First District Local Notice to Mariners.

Mariners who have questions, comments, or concerns about the planned waterway closure are encouraged to contact Lt. Matthew Odom, Coast Guard Sector Northern New England, Waterways Management Division Chief, at or (207) 347-5015.
