Abstract: This article focuses on short-span bridges and describes ways in which they can be economically rehabilitated. It discusses how plans for pre-designed bridge structures can call for lighter foundations. The article points out some of the advantages in timber bridges that are made available by new technologies such as glued-laminated timber, fiber-reinforced wood, or dowel-laminated technologies. Concrete foam panels or precast concrete inverted T-beams are described as being cost-effective methods. Deteriorated bridges and culverts can also be rehabilitated by using flowable fill which is noted for its cost- effectiveness, enhanced structural integrity and safety, and its role in expediting the return to normal traffic flow.
