I can’t give you a correct answer on this because I really dont know but the longest bridge I know of is the Newport bridge in Rhode Island
and the Newport bridge is 1 mile long LOL
Its the bridge between Denmark and sweden
In the US, it’s the bridge over Lake Pontchartrain just northwest of New Orleans. 28 mi.
I think “allen_o” has it right…. What does he win? I gave him a “Great Answer”...
who cares cause I will be terrified on that bridge.
