A1 Haddington to Dunbar Expressway, East Lothian Also finalist for the Prime Minister's Better Public Building Award This substantial widening of the A1 in Scotland has been designed to follow the route of the existing highway except for a spectacular crossing of the Tyne on a 217m long, three span post-tensioned concrete bridge. The bridge was cast on what is claimed to be the largest scaffolding falsework ever used in Scotland. The mode of construction enabled minimal web cross-sections of high strength concrete to be used for the permanent structure.

Balfour Beatty Civil Engineering with design by Scott Wilson Scotland A650 Bingley Relief Road, Yorkshire Also finalist for the Prime Minister's Better Public Building Award.
History of the Bingley Relief Road goes back three decades to the frustrated plans for the Aire Valley motorway and vocal road protest movement of the 1970s. In the years since, Bingley became choked with traffic and coincidentally its mills fell into dereliction. Today's relief road is designed and built to ease traffic congestion while at the same time cleaning up contaminated sites, preserving natural habitats and being a catalyst for town revival.

Tarmac; Fairfield Mabey; CV Buchan; Butterley Engineering Masshouse Circus redevelopment, Birmingham Also finalist for the Prime Minister's Better Public Building Award In effect Masshouse Circus is exactly the opposite of the new Bingley Relief Road. Completed at the apogee of urban road construction as part of the Birmingham Inner Ring Road, Masshouse was a prime example of the genre - an agglomeration of ugly elevated concrete structures which created a collar around the city and an underworld avoided by the community. Maintenance of the salt-damaged structures also became a continuous burden. Now the whole lot has been demolished so that a fresh start can be made.

A pair of environmentally acceptable open channels running 3km around the west end of the airport have been created to an exceptionally high standard and within budget, for £45M. Water quality has improved as have the surroundings thanks to the sowing of plants in the water using palletised bags and the import of many mature trees.
