This article reports some contractors' views of what can be learnt from two of the first contracts in the UK's new programme of motorway widening. The contract to add a fourth lane to the busiest part of the M25 in London provides lessons which will be vital if the emerging road widening industry is to minimize its economic and public impact. The M25 widening contract had three times the cost and duration of any previous road reconstruction project by its contractor, and involved over 8 km of overloaded motorway. The consultant must develop a works plan but provide the contractor with scope for any necessary amendments. At least four weeks' planning time should be allowed between contract award and start of work on site. Because small setbacks in construction can have large implications, consultant's and contractor's staff should be enabled to take quick decisions first and argue about costs afterwards. Many road builders are concerned about the enormous traffic disruption that could result from rushing jobs in the design and planning stage. Contractors are urging the Department of Transport to begin to plan road contracts to suit the seasons when the road works are to be done, rather than politics or money.
