The thousands of drivers who use a Rhode Island highway on their way to work every day probably have no idea they are passing over the graves of some people who died in the late 1800s and early 1900s at state institutions. The location of the graves beneath the highway in Cranston, Rhode Island, was publicized in a WPRI-TV story Monday about a woman searching for the gravesite for her great-great-grandfather. Route 37 was built in the 1960s over part of the institution cemetery. The state DOT says 1,000 of the graves should have been moved.
