Abstract
The Coast Guard is temporarily modifying the operating schedule that governs the Dearborn Street Bridge, mile 1.13, over the Main Branch of the Chicago River at Chicago, Illinois. During this maintenance period, the bridge need only operate one leaf while the other leaf remains secured to masted navigation. Vessels able to pass under the bridge without an opening may do so at any time.
