Transport for London (TfL) announced last week it plans to refurbish the Gallows Corner flyover – initially intended as a temporary structure when built in the 1970s.
It is now in poor condition and requires major strengthening and refurbishment to continue operating safely, TfL said.
Heavy goods vehicles (HGVs) are unable to use it, and there is a permanent speed limit of 20 miles per hour.
The works to renew it will last several months, with phase one seeing lane closures when it begins next week.
Barry Mugglestone, Havering Council’s cabinet member for environment, said: “We have been lobbying for improvements for many years, and we are pleased that there are now plans to refurbish the flyover.
“It will clearly lead to massive issues for the borough on our roads when it is closed, as the Gallows Corner junction is a major artery used by residents, businesses, and those travelling in and out of London.
“It will be a massive pain, but when completed, we hope that this investment will see improved journey times for all.”
Once refurbished, the flyover will be able to carry HGVs again, and the speed limit will increase to 30 miles per hour.
The refurbishment intends to extend the life of the flyover by a further 60 years and reduce the need for temporary repairs and closures.
There will also be changes to the lane layout on the roundabout, which TfL says will improve traffic flow and safety at the junction.
The council said it will be working closely with TfL to inform residents, businesses, and drivers who use the roads in the area throughout the works to mitigate the disruption the scheme will cause.
Council leader Ray Morgon said: “This has been a long time coming, as the Gallows Corner flyover is literally on its last legs.
“We therefore welcome that it will finally see a major refurbishment as it is an integral part of the borough’s infrastructure.”
Some council services, including transport for people with special educational needs and disabilities and rubbish collections, are likely to be affected due to the road closures.
Councillor Mugglestone added: “We will continue to lobby for further improvements to the roundabout below the flyover, as currently it is very difficult to navigate and for many it feels unsafe.
“TfL are listening to us and, whilst we welcome plans for new pedestrian crossing facilities, we look forward to seeing if there will be additional changes.
“Although we accept the fact that the junction will be better as HGVs will be able to use the flyover, we also hope there are no major delays to the works starting and finishing as that would cause absolute chaos in the borough.
“We will be working closely with TfL to ensure they deliver this project on time and with the least amount of disruption to residents as possible.”
The announcement of the project was also welcomed by Hornchurch and Upminster MP Julia Lopez.
Ms Lopez said: “Its renewal is crucial to ensure the safety and efficiency of our local transport network.
“While there will be some disruption during the construction period, the long-term benefits of a safer, more reliable flyover will be well worth it.”
Enabling works, including lane closures at the roundabout, are scheduled to begin from March 10.
