SCDOT, USDOT Break Ground on I-95 Bridges Over Lake Marion Replacement Project

CLARENDON COUNTY, SC — The South Carolina Department of Transportation (SCDOT), in partnership with the U.S. Department of Transportation (USDOT), announces the groundbreaking of the Interstate 95 bridges over Lake Marion replacement project in South Carolina. The project will replace the existing northbound and southbound bridges over Lake Marion, originally constructed in the 1960s, with modern structures designed to improve safety, reliability, and mobility along the I-95 corridor. This critical route serves as a major artery for freight and passenger travel along the East Coast.

The project is supported by a $175 million federal investment made possible through one of the largest federal discretionary grant awards ever received by SCDOT.

“[This] groundbreaking is a proud moment for Team South Carolina and a testament to what can be accomplished when state and federal partners work together to deliver for the people of South Carolina,” South Carolina Governor Henry McMaster said. “These new bridges will strengthen one of our most important transportation corridors, improve safety for drivers, and help drive continued economic development across our state.”

I-95 is one of the most heavily traveled interstate highways in the nation, connecting major markets from Florida to Maine. The Lake Marion bridges are a vital link in that network, carrying thousands of vehicles each day, including a significant volume of commercial traffic.

“This project represents a major milestone for South Carolina and for everyone who relies on I-95,” said Justin Powell, Secretary of Transportation for SCDOT. “Replacing the Lake Marion bridges ensures we are delivering a safer, more reliable corridor that supports economic growth and keeps people and goods moving efficiently through our state for decades to come.”

The project includes full replacement of both bridge structures and improvements to the surrounding roadway approaches.

Once complete, the new bridges will meet current engineering standards and provide long-term durability with reduced maintenance needs. Construction is expected to take several years, with work phased to minimize disruptions to traffic along this vital interstate corridor.
