Eastman had his relatives and friends build their houses on the island, and built the Eastman and Grove Street Flats. Eastman's efforts lead many of the city's Gilded Age wealthy to live on the island, in the later decades of the 19th century. In 1876, a replacement suspension bridge across the Mississippi was opened. In 1867 the first railway bridge across the Mississippi in Minneapolis was built, separating the industrial south of the island and the residential north, as the Minneapolis BNSF Rail Bridge (an 1893 replacement) still does.
