The Maryland Transportation Authority will open bids Sept. 22 for rewrapping, dehumidification and security shielding of the main cables and anchorages on the state’s two Bay Bridges—a project valued at $30 million to $50 million.

Work on the first span began in 1949, following 40 years of planning and discussion.

The work includes both of the twin 4.34-mile-long eastbound and westbound suspension bridges—officially, the William Preston Lane Jr. Memorial Bridge—over the Chesapeake Bay.

Scope of Work

The project involves rewrapping the main cables and anchorages and spot-coating anchor bars and miscellaneous steel on both bridges, as well as exterior roadway girders at the anchorages on the westbound structure.

The four-and-a-half-year contract includes 30 months for construction and 24 months for maintenance.

A signed confidentiality agreement must be provided before receiving the RFP documents.

The bridge’s two-lane original span (which now carries eastbound traffic) cost $45 million and was the world’s longest continuous over-water steel structure when it opened in 1952. The bridge replaced a 23-mile, two-hour ferry service that had run since 1919.

The second span, which now carries westbound traffic, opened in 1973.

Construction of the bridge’s $148 million second span, 450 feet north of the original span, began in 1969 and was completed in 1973. The second span now carries westbound traffic.

J.E. Greiner Co. Inc. designed both bridge spans.
