Building a new Key Bridge could take years and cost at least $400 million, experts say

Rebuilding Baltimore’s collapsed Francis Scott Key Bridge could take anywhere from 18 months to several years, experts say, while the cost could be at least $400 million — or more than twice that. Realistically, the project could take five to seven years, according to Ben Schafer, an engineering professor at Johns Hopkins University. Others are more optimistic about the potential timeline: Sameh Badie, an engineering professor at George Washington University, said the project could take as little as 18 months to two years.
