The Savanna–Sabula Bridge was a truss bridge and causeway crossing the Mississippi River that connected the city of Savanna, Illinois, with the island city of Sabula, Iowa. The bridge was put out of service on November 17, 2017, when its replacement, which lies a few dozen feet downstream, opened as the Dale Gardner Veterans Memorial Bridge. The bridge carried U.S. Route 52 over the river. It was also the terminus of both Iowa Highway 64 and Illinois Route 64. The bridge carried an average of 2,170 vehicles daily as of 2015, with 6% of that being truck traffic.
