The Illinois Department of Transportation is the lead agency on replacement of the Centennial Bridge, US 67 across the Mississippi River<\/a>. There will be an open house on May 20 from 3 to 6 PM at the Holiday Inn in Rock Island on the corridor study, the Illinois DOT says<\/a>, in a press release reprinted by the Iowa DOT. The bridge, built in 1940, is the most traveled structurally deficient bridge in the state.<\/a><\/p>\n

Materials from the first two meetings are available online<\/a>. There are four non-replacement options on the table: Default no-build (obviously not acceptable), rehabilitation (addresses some issues but not all), a parallel twin structure combined with rehabilitation, and reconstruction, which involves taking apart the entire superstructure while widening the concrete piers in the river.<\/p>\n

Replacement options are down to two. One is slightly downstream and parallel to the present bridge. The other is completely different, coming straight off 11th Street in Rock Island and running virtually true north-south across the river, spilling onto Marquette Street in Davenport. This plan would require using 2nd Street between Marquette and Gaines streets to get back to the Gaines connection to River Drive.<\/p>\n","protected":false},"excerpt":{"rendered":"
