Westbrook handled construction administration for a bridge reconstruction project on Fish School Road over the Branch Knapp Creek in the Town of Sylvan, WI. Westbrook was onsite day-to-day for construction inspection and project managerial duties. The 34-foot span bridge took 143 cubic yards to construct and features a 24-foot clear roadway width between bridge railings. The project lasted from mid-May until Mid-July.
Westbrook designed the temporary works required to construct a new bridge over the Illinois River in Spring Valley, IL. Designs included five cofferdam designs, a platform design to support a drill rig on top of the cofferdam, and stability calculations for a 330 ton crane working from a barge. Design calculations and plans were also developed for the erection of temporary bents used to facilitate the placement of the steel plate girders, as well as lifting calculations to bring the girders from the ground to their proposed locations on the temporary bents and existing piers.

Westbrook was contracted by Lunda Construction Company to design temporary measures to facilitate the removal of the old five-truss span and to allow for the roll-in of the new 300′ long bridge truss over 13 live railroad tracks for the St. Anthony Parkway Bridge in Minneapolis, MN. Temporary measures entailed multiple temporary bent designs, girders for supporting the rolling truss, and cribbing and lowering jack systems to set the truss on the new piers.
