Balfour Beatty Investments operates and maintains a 30km dedicated highway link which provides strategic connections between the M1 and M62 motorways to the south of Leeds and the A1 Trunk Road south of Wetherby. Construction included 18km of new roads, widening 12km of existing roads, two interchanges, five junctions and 169 structures, comprising two tunnels, 14 overbridges, 19 underbridges and one viaduct.
In addition to the construction of the M1-A1 motorway Link Road, the project included widening and improvement of the M62 east of Junction 28 to Junction 29, Lofthouse Interchange, the M1 from Junction 42 to Belle Isle and the upgrading of the A1(T) from Micklefield to Bramham to motorway standard.
There were also unique requirements in respect to landscape areas. A Site of Special Scientific Interest falls within the project facilities and wildlife links were addressed by the construction contract and subsequently added to and enhanced. The M1-A1 motorway project opened three months ahead of schedule in 1999.
