The Rhode Island Turnpike and Bridge Authority was created in 1954 by the Rhode Island General Assembly as a body corporate and politic, with powers to construct, acquire, maintain, and operate bridge projects as defined by law. The Rhode Island Turnpike and Bridge Authority operates and maintains the Mount Hope Bridge, the Jamestown Verrazzano Bridge, Route 138 through Jamestown, the Newport Pell Bridge, and the Sakonnet River Bridge.
