Residents, businesses and motorists have been left in the dark for more than two months after TfL announced a delay to the project in August.
Now, TfL has released a statement confirming that it “intends to complete works at Gallows Corner flyover by spring 2026” across three phases.
Phase one and two involve the completion of the flyover and the installation of the water main alongside it, with Essex & Suffolk Water planning to work outward from the roundabout.
Only once these phases are complete will the flyover be reopened to drivers – but the roundabout and surrounding roads will remain closed during phase three.
Phase three involves the final water main diversion and highway improvements to the A127; completing this phase will lead to the full reopening of the junction in the “following weeks”, TfL said.

Scott Haxton, TfL’s director of capital delivery, said: “We’re incredibly grateful to residents and businesses for their continued patience while we carry out these essential works at Gallows Corner.
“We understand how disruptive this has been, and we’re working with our partners to complete the project as quickly and safely as possible.”
Alastair Tawn, head of integrated delivery services at Essex & Suffolk Water, added: “We appreciate the importance of this busy road interchange and are sorry for the inconvenience caused.
“However, I can reassure people who live, work and drive in the area, that this remains a priority for us and our team continue to make good progress in line with our new programme.”
Gallows Corner shut more than four months ago, causing “serious delays” on surrounding roads, “drying up sales” for nearby businesses and leaving some residents “struggling” to pay their bills.
The closure – prohibiting all traffic except emergency vehicles, TfL buses and black cabs from entering the major roundabout – is in place to allow for the replacement of the “ageing” flyover.
Alongside this, Essex & Suffolk Water have been replacing one of its older water mains which runs underneath the A127 – however, its plans to do so were only made clear in July.
Up until August 16, TfL told this paper that works were “still on schedule to finish in September”.
But, just less than two weeks later, Mr Haxton announced a delay to the project due to “unforeseeable problems” with the ground condition around the water main.
At the time, a spokesperson for Essex and Suffolk Water said it was continuing to work closely with TfL to “ensure our programmes remain aligned through the remainder of the works on both infrastructure projects”.
