Some Portal Frame Bridges in Oxfordshire

DURING the last few years the Oxfordshire County Council has been engaged on a number of schemes of road improvements involving the building of bridges. In five of these schemes, six bridges in all, certain advantages have been obtained by the adoption of
the portal frame. Space does not permit of a detailed description of these bridges, and only those featmes which illustrate the advantages obtained from the portal frame, or which are otherwise of special interest, will be described.
