Toll roads built 70 years ago were supposed to be free by now but are still toll roads as the states cannot give up that cash cow!
The bridge was already a toll bridge. It's owned by the Maryland Transportation Authority, which owns and runs all the tolled facilities in the state, such as the Intercounty Connector (MD 200), the Kennedy Highway (I-95 northeast of Baltimore) and the Nice Bridge that takes US 301 into Virginia.
Then it will get replaced quickly.
