MDTA gets final approval for Chesapeake Bay bridge replacement project

The Maryland Transportation Authority (MDTA) announced it has received final federal environmental approval for its Chesapeake Bay Crossing Study, according to FOX 5 DC. This approval clears the way for the construction of two new four-lane bridge spans with full shoulders across the Chesapeake Bay, replacing the current bridges.

The Federal Highway Administration selected Alternative C as the preferred plan, which MDTA identified as the most cost-effective option. The project includes removing the existing bridge spans and is expected to improve safety, increase capacity, and enhance travel reliability across the bay.

MDTA plans to begin design work in 2028, with construction potentially starting as early as 2032. The new bridges will provide 230 feet of navigational clearance, matching the height of the Francis Scott Key Bridge, allowing larger ships to access the Port of Baltimore.

The project also involves widening U.S. 50/301 to eight lanes to accommodate traffic transitions to the new spans. Additional components include a one-time investment of up to $40 million for transit improvements, land preservation efforts on the Eastern Shore, and a possible bicycle and pedestrian path.

Officials estimate the project will add $23 billion to the local economy and create more than 60,000 jobs. Environmental documents related to the project are available online at baycrossingstudy.com.
