Poland Bridge Rehab Progress [WGN 45-08-02]. February 7, 2004 - The new curbing has been installed leaving a roadway 9 feet 8 inches wide. With this addition to the bridge dead-load and a week in which the timbers have been settling under the weight of the structure, the camber has decreased two-and-one-quarter inches to 14 3/4 inches.        Next, two-inch oak running planks will be laid down in the roadway to protect the laminated flooring. The runners will each be 40 inches wide.        Steel clamps will be installed to hold nailers in preparation for the new siding. The roofing will go on when the structure has adjusted to this additional dead-load and the camber has stabilized.        By mid-day Monday most of the steel scaffolding has been removed, an essential step as spring approaches--when the ice begins to move, the scaffolding standing in the river bed could have caused an ice jam dangerous to the bridge. By mid-day Monday most of the steel scaffolding has been removed. Photo by Joe Nelson, February 7, 2004 The new curbing has been installed leaving a roadway 9 feet 8 inches wide.
