Abstract


This article presents a very versatile structural solution to the problem raised by existing overpasses on motorways which require road widening works or an increased number of traffic lanes. The proposal, consisting on the overpass span’s enlargement, overcomes the difficulties imposed by the combination of works required to retain the entire deck of the overpass without demolition work while keeping both the motorway and overpass open to traffic.
