Iowa solves problem of widening narrow bridges
1200 bridges totaling nearly 26 mi in length are being widened; pony trusses and simple I-beam bridges made up bulk of work; to modernize X-series bridges, old truss span is pushed over about 15 ft to one side, one or more concrete pile bents are driven and one-half of continuous concrete slab bridge is built on bents and old abutments.
