As ships grow and seas rise, can Baltimore’s port use new bridge to raise the roof?

Baltimore’s corner of the Chesapeake Bay has had a fixed ceiling of sorts — the 185-feet vertical clearance of the area’s bridges — for the past 70 years. Soon, authorities will decide if they want to raise that limit and by how much. It’s a once-in-a-century opportunity, a decision that will define the vertical limits of the corridor for decades.
