The Maryland Transportation Authority is launching two multi-million-dollar preservation projects on two of its Baltimore-area toll facilities -- the Francis Scot Key Bridge and the Harbor Tunnel Thruway.
The authority plans to spend $6.8 million to clean and paint exposed steel surfaces, repair drainage troughs and make other repairs at the Key Bridge. The work is expected to be finished in summer 2013.
Another $3 million will go toward underwater repairs and other maintenance work on the Interstate 895 bridge over the Patapsco River -- about 2 1/2 miles south of the Harbor Tunnel. According to the agency, there has been some erosion in the bridge structure in the river. The project is expected to be completed in fall 2013.
The projects are financed with toll revenue collected at the authority's eight highways, bridges and tunnels. The agency said the work may involve lane closings at off-peak travel times, but not on days leading up to or following major holidays.
