This job involved the replacement of a bridge over the Western Region Railway between junctions 9a and 9b of the A404 near Maidenhead.

The difficulty of this job was that the bridge had to be demolished and replaced whilst staying open for traffic ,with the added complication of a four-line railway below.

This was achieved by demolishing and rebuilding the bridge in sections which ensured that four lanes of traffic could still flow at all times.

Lorclons input into the often complex operation included the construction of bridge abutments, wing walls, trestle bases, VRS bases, backfilling and road construction.
