Defying Nature - The Barrier Today

From its groundbreaking on Nov 17, 1962 to dedication ceremonies May 21, 1966, nearly 1,000,000 hours of labor, planning, testing, and finishing went into the project. At the time of construction, the Barrier protected some 30+ industries employing more than 10,000 people. The goal was to provide future flood security for these industries, the fishing fleet vital to this area, and hundreds of coastal homes.

Protection from Surging Waters​

The barrier consists of three principle features:

1. Clark’s Cove Dike

2. Harbor Barrier and Extension Dike

3. Fairhaven Dike

Collaborative Operations

The city of New Bedford maintains and operates the majority of the project with two exceptions.; the sector gates across the navigation channel and the harbor barrier are operated and maintained by the U.S. Army Corps of Engineers, and the Town of Fairhaven maintains the Fairhaven Dike.




Today, the top of the barrier provides a walkway for recreational activities. Opened in 2015, the New Bedford Harbor Walk is 3,880 feet long. Connecting with a bike path running along the waterfront into historic Fort Taber Park, the path gives visitors an expansive view of Buzzard Bay.

In 2017, a 5,550-foot CoveWalk opened atop the hurricane barrier on the western side of the peninsula, overlooking Clark’s Cove. Currently, plans for a new RiverWalk are underway; the 17,000-foot recreational waterfront path will be developed on the upper harbor, along the western bank of the Acushnet River north of the New Bedford-Fairhaven Bridge.

Closing the Gates

The hurricane barrier has prevented over $37.9 million in flood damages since its construction. Although the gates close up to a dozen times a year for storm events that bring tidal surges, a closure for a hurricane is rare.

The Hurricane Barrier located here in New Bedford Harbor, designed and built by the US Army Corps of Engineers in 1962, is the largest and most sophisticated barrier in the world. Since its construction, it has yet to be given the ultimate test.”

Explore Local Sea Level Rise

Given the ever-changing port economy, rising sea levels, and more frequent storms, it’s important to evaluate the potential impact of climate change our local landscape.

Survey sea level rise and potential coastal flooding impact areas.

  • Compare inundation levels to local relative sea level rise scenarios
  • Survey potential changes in march and other land cover types 
  • View potential impact of coastal flooding on a vulnerable population
  • Explore areas susceptible to high tide flooding and historical flood events

The National Oceanic and Atmospheric Administration (NOAA) National Hurricane Center, in partnership with the U.S. Army Corps of Engineers (USACE), uses the Sea, Lake, and Overland Surges from Hurricanes (SLOSH) model to calculate the storm surge heights and map coastal areas with the highest degree of exposure. Visit to learn more.
