WSOR :: 2007 Bridge Projects

2007 Bridge Repair/Rebuilding Program

Twenty bridge repair/rebuilt projects across the entire WSOR system were completed during the year 2007. Work has varied from replacing pile cap bents to building entirely new bridge decks. The projects were distributed as follows: Markesan Subdivision: 1; Prairie Sudivision: 6; Monroe Subdivision: 8; Fox Lake Subdivision: 4; Reedsburg Subdivision: 1. Below is a summary of several of the key projects for the year 2007 to give an idea of the scope of our work.
