Overline Bridges

New bridges over the railway designed by Cass Hayward include bridges for highways, footways and cycleways as well as some rail intersection bridges. Our designs have been for new routes and highway improvements as well as for railway gauge clearance projects and replacement of life-expired structures.

Our most prominent project has been for the widened reconstruction of the long spans of Bishops Bridge Road bridge over the ends of the platforms at Paddington Station in London and we designed the landmark arch bridge carrying Newport Street at Bolton Station. More recently our design for the new access bridge into Emanuel School near Clapham junction was developed to allow its launch erection and has special architectural parapets.

Since 2007 twenty five new over-line bridges have been constructed to our designs for Railway Gauge Clearance projects. Most are bridge reconstructions for highway bridges with special challenges associated with dimensional constraints, site restrictions and existing services. Slender designs with high containment parapets are required and this experience has allowed us to generate a family of designs which can be adapted to these exacting circumstances.
