Low maintenance and rapid construction were key design considerations for the recently opened Halgavor Bridge near Bodmin. High durability glass reinforced plastic (GRP) materials were chosen for the deck of the suspension bridge, which has cranked steel masts.

The crossing - part of the National Cycle Network - is designed to be integral with the abutments at each end and has no expansion joints. The low modulus of the GRP deck results in relatively low axial forces arising from thermal expansion and contraction, which are easily accommodated.

Balfour Beatty Construction's regional civil engineering business carried out the design and construct contract, with Flint and Neill Partnership as its engineering consultant.
