An invitation to contractors to pre-qualify for each project will follow shortly.
Contractors will complete the design of each scheme, fund construction and be responsible for managing and maintaining the new and associated existing roads for 30 years.
In return, the Highways Agency would pay 'shadow tolls' to the contractors on the basis of the number of vehicles using the project road.
M40, Junction 1 near Denham, Bucks, to Junction 15 near Warwick, including the rapid widening to four lanes of the section between Junctions 1A and 3 (cost £40m). The overall length of the project road is 76 miles;
A19/A168 Tyneside to A1 Junction at Dishforth, including the widening to dual three lanes of the section between Norton and Parkway in Cleveland (cost £30m) and responsibility for maintenance of the Tees Viaduct. The overall length of the project road would be 74 miles;
the replacement of the A30 between Honiton-Exeter (cost £55m) and the construction of the A35 Tolpuddle and Puddletown Bypass (cost £20m), with the management and maintenance of A30/A35 trunk road between the two schemes, a total length of 58 miles;
the Stoke-Derby corridor including the building of A564 Doveridge Bypass (cost £20m) and an option to operate and maintain the Derby Southern Bypass once its construction is complete, a total length of 35 miles.
Welcoming the decision Mr Watts said:
'The enthusiastic response last year to our first four DBFO contracts, now out to tender, encourages us to extend the range of projects to be built and managed by the private sector. Private finance has already contributed significantly to improving our infrastructure, for example at Dartford.
'We now want to extend their expertise into the management of important roads. So while each of these further DBFOs contains significant new construction, they also focus on the management of existing trunk roads and motorways.
'As before, our object is to deliver a high quality service to the travelling public'.
Pre-qualification documents will be available in about 10 days time and submissions from potential bidders are invited by early April. Tendering will follow in the early summer of 1995.
