- General information. There are records of only five authentic covered
bridges that were built between 1820 and 1867 in the state of Rhode Island.
Rhode Island does, however, have the distinction of having the first covered
interstate railroad bridge in the United States. It was the India
Point Covered Bridge, built across the Seekonk River for the Boston and
Providence Railroad. Of the five covered bridges, two were highway
and three were railroad. The last of the covered highway bridges
was replaced by a wide concrete bridge in 1920. Today, there are
seven non authentic and one modern authentic covered bridges in Rhode Island.
Four of these are highway and four are footbridges.
