National Highways’ £23M project to replace a bridge over the M67 will see the installation of four pairs of steel beams on the weekend of 4 to 7 April, requiring a part closure of the motorway.
St Anne’s Road bridge across the motorway in Denton, Greater Manchester was identified as a safety risk due to its age and had to be replaced. The prior phase of the project included the successful demolition of the bridge, completed by principal contractor Tilbury Douglas at the end of last year. This involved the removal of the main deck and upper parts of the abutment walls that flank the structure. Modifications to these walls have been ongoing to prepare for the new installations.
The new braced steel beams weigh over 250t collectively and will support the new bridge deck. Each pair of braced beams weighs up to 65t and measure 34m in length, 3m in width and 1.5m in height. Two cranes will be employed to safely place these beams into position.
The replacement of the bridge is crucial not only for improving road safety but also for ensuring unrestricted access for all motorists, particularly enhancing eastbound access to the motorway.
The St Anne’s Road bridge has long been a critical conduit for essential utility services including water, gas, electricity and telecommunications, serving a wide area across Greater Manchester. Work to re-route these services was completed earlier.
The construction sequence for the bridge replacement can be seen in the below video.
To facilitate the upcoming work, the M67 section running beneath the bridge will be closed in both directions from 9pm on Friday 4 April, until 5am on Monday 7 April. This closure will affect the stretch between junction 1A at Denton and junction 3 at Hyde and is the final planned weekend closure for the bridge replacement.
Following the installation of the steel beams, the project will transition into the next phase, which includes the construction of the new bridge deck. Some additional overnight closures of the motorway will be necessary to ensure the safe completion of this critical infrastructure project.

National Highways programme delivery manager Mangat Bansal said: “This final weekend closure will allow our teams to safely install the eight steel beams which will carry the new bridge across the motorway.
“It is imperative we keep the travelling public and our workforce safe. To achieve this, we need to close the motorway for the weekend to allow for the heavy machinery needed to undertake this work to be brought in.
“We always strive to minimise disruption, although regretfully delays to journeys are expected. We therefore advise everyone to plan before they travel and allow extra time. We apologise for any inconvenience this work will cause and thank people for their support and patience while we continue our work.”
