The Quiz: The Foster Covered Bridge, seen in today’s photo, is in Vermont, a state with more than 100 covered bridges. Which state has the most?
A New Hampshire
B Pennsylvania
C Iowa
There are fewer than 900 covered bridges left in the US and Pennsylvania is home to about 200 of them. Why put a roof on a bridge? It comes down to longevity—the roof helps protect the timber supports from rot. An uncovered wooden bridge may only have a lifespan of about 20 years while a covered bridge could stand for more than 100. A few covered bridges in the US are closing in on their 200th birthdays.
The correct answer to this quiz is Pennsylvania.
