Graham has secured a £124m contract from Highways England to design and build critical improvement work to junction 28 of the M25 between the M25 and the A12 in Essex.
Main construction works are set to start this spring between Brentwood and Romford.
Significant features of the improvement works to be delivered by Graham include:
A new two-lane loop road with hard shoulder, for traffic travelling from the M25 to A12
Works on A12 eastbound to maintain existing access to Maylands Golf Course
An overbridge at A12 eastbound exit road to allow the proposed loop road to join the A12 eastbound carriageway
Widening of the M25 anti-clockwise carriageway to provide proposed exit road
A bridge over the M25 anti-clockwise entry road to facilitate a new loop road
M25 junction 28 is a heavily used junction which features a roundabout mainly controlled by traffic lights. It is already operating at full capacity, with traffic queues and lengthy delays caused by up to 7,500 vehicles per hour currently travelling through it at peak times.
The award is Graham’s latest Highways England win with the contractor delivering improvements to Junction 25 of the M25 and Junction 5 of the M2.
Dave Brown, Highways Director at Graham, said: “This is another significant scheme for us to be awarded and last of the three schemes to sign in the package following signing of the M25 Junction 25 and M2 Junction 5 schemes.
“It is testament to our growing reputation in the highways sector that we have been chosen as contractor for another important improvement scheme in the south-east of England. “We have enjoyed an excellent relationship with Highways England for many years, built on collaboration.
“By delivering this scheme we’ll be catering for the road’s future traffic demands, increasing capacity and reducing congestion.
“The improved link to the A12 will also enable development and support economic growth, providing significant benefits to the area.”
