Transport for London (TfL) has confirmed that the major works to rebuild the Gallows Corner flyover are now expected to be completed by spring 2026 — with the flyover reopening to traffic first, followed shortly after by the roundabout and surrounding roads.
Julia Lopez MP has expressed disappointment at the extended timeline, describing the news as “another frustrating setback” for residents and local businesses who have faced prolonged disruption and uncertainty.
TfL previously committed to providing a clear update by the end of October, but this was delayed. Following continued pressure from Mrs Lopez, TfL has now shared details of the revised programme.
The project involves the complete renewal of the 1970s-era temporary flyover to ensure the long-term safety and reliability of this key junction on the A127–A12 corridor. To minimise future disruption, TfL is coordinating its work with Essex & Suffolk Water, which is replacing an ageing strategic water main that runs beneath the flyover.
However, the project has faced multiple complications, including poor ground conditions, the presence of localised shale, and the discovery of two uncharted gas mains. These issues have forced significant redesigns and changes to construction sequencing, pushing back the overall completion date.
Under the new schedule, the project will be delivered in three main phases:
- Phase 1: Completion of bridge sections over the roundabout while Essex & Suffolk Water finishes installing a new water main beneath it.
- Phase 2: Final foundation works and bridge surfacing to allow the flyover to reopen to traffic in spring 2026.
- Phase 3: Completion of water main diversions and highway works on the A127, enabling the full reopening of the roundabout and surrounding roads.
Mrs Lopez said:
“Residents have been incredibly patient, but confidence in this project is understandably low after months of missed deadlines and limited communication. While I welcome TfL’s latest statement as it now gives us something to work with, spring 2026 remains vague. I will continue to press them to keep local people properly informed and ensure the project does not face further delays. Businesses in particular need clarity so they can plan ahead, and I will keep holding TfL and the Mayor’s office to account to ensure progress is maintained.”
TfL has committed to providing further detail on reopening timescales early next year, alongside continued engagement with local stakeholders and updates through its dedicated project webpage.
Mrs Lopez continues to stay in close contact with TfL, Essex & Suffolk Water and the Deputy Mayor’s office to ensure that local residents’ voices are heard and that the project remains a priority for London’s transport authorities.
