CHATHAM- BRIDGE REPLACEMENT, C-07-001, BRIDGE STREET OVER THE MITCHELL RIVER

The purpose of the project is to remedy the bridge’s structural deficiencies and functional obsolescence, while keeping with the context of the surrounding area and accommodating all existing and future uses of the bridge. The current alternative consists of an all timber superstructure (including the wearing surface, structural deck, beams, sidewalks, and railings) with the exception of the bascule leaf which will consist of a steel frame. The superstructure would be supported on pile bent substructure units constructed with concrete-filled steel piles and concrete caps. The bascule span superstructure consists of a timber roadway deck and sidewalks on steel open grid flooring panels on the concrete bascule pier substructure. Additional improvements include transitioning and resurfacing of the approach roadways. The navigable channel will also be shifted 5 feet to the west and widened to provide 25 feet of horizontal clearance, fender to fender. Vehicular and pedestrian traffic will be detoured during construction.
