There’s a $592 million project coming for a bridge on a CT interstate. It won’t be done until 2029.

It’s a $591.9 million, multi-year project on a Connecticut interstate.

The northbound deck of the Gold Star Memorial Bridge needs to be replaced, and a public information meeting will be held April 30 to provide the details and offer an opportunity for questions.

The bridge links New London and Groton across the Thames River on Interstate 95.

“The Gold Star Bridge is a vital structure for New London and Groton residents, major employers, and freight movement along the I-95 corridor,” said state Department of Transportation Project Manager Tracey Brais in a statement.

“This project will address existing bridge deterioration, increase the bridge’s load carrying capacity, and extend its service life,” Brais said. “We encourage the public to attend this meeting to share their feedback with the CTDOT project team to incorporate into the design.”

The project will replace the deck and strengthen the steel superstructure to improve freight travel across the Thames.

It will increase the structural capacity of the bridge, improve safety and continue to meet the traffic demands for the region, according to the statement. The U.S. Naval Submarine Base , and the United States Coast Guard Academy are both nearby and I-95 is a major corridor through New England.

Construction will begin in summer 2025, assuming funds are available, rights of way are acquired and permits are approved.

The estimated construction cost is $591.9 million, including $158.2 million in Bridge Investment Project Grant funds , 90% federal funds and 10% state funds. It is scheduled to be completed in March 2029.

The Gold Star Memorial Bridge was originally constructed in 1943, and a major superstructure rehabilitation was performed in the 1970s.

In the 1990s, multiple rehabilitation projects were completed to improve bridge conditions. In 2014, there was a bearing replacement project for half of the expansion bearings on the approach spans. In 2018, improvements were completed on the southbound span. In 2020, the project on the northbound span began.

The hybrid meeting will be held at 7 p.m. at the Groton Municipal Building, 295 Meridian St. It will be offered on Zoom as well. To register for Zoom, go to https://bit.ly/gold-star-bridge . The meeting also will be livestreamed on YouTube at portal.ct.gov/ctdotvpimarchive . No registration is required for YouTube.
