Baltimore survived before the bridge, and they will survive afterwards. Cheaper just to send the traffic around the harbor. Expand whatever beltway is there a couple of lanes.
That was the function of the Francis Scott Key bridge, built in the 1970s,
Expand whatever beltway is there a couple of lanes.
Do I understand correctly that you don't live within 1000 miles of Baltimore, have never been to Baltimore, and have no knowledge whatever of the Baltimore traffic pattern?
Apparently you’ve never been here. The bridge was part of the beltway that you think will be easy to expand. The other way is heavily populated. Eminent domain will take years. Dozens of bridges will need to be replaced and about 30 ramps rebuilt.
What they should do is to lease a couple ferry’s and have limited ferry service for HAZMATS and vehicles with a destination less than five miles from the bay.
There are two tunnels already. One should be restricted to commercial traffic, especially during peak hours.
