Transport for London’s latest published timeline says Gallows Corner is expected to fully reopen in spring 2026 , with the flyover opening first and the roundabout and surrounding roads following a little later.

What “reopen” actually means

  • The flyover is planned to reopen to general traffic first, once surfacing and waterproofing are complete, currently targeted for spring 2026.
  • The roundabout and surrounding approaches are then due to reopen in the weeks after the flyover, still within that spring 2026 window.

Why it’s taking so long

  • The main cause of delay has been unforeseen issues with a major water main replacement being done alongside the flyover renewal, which has pushed back key construction stages.
  • Local councils and MPs have publicly pressed TfL and Essex & Suffolk Water for a clearer schedule because earlier reopening dates were missed and disruption has been severe for residents and businesses.

What to expect until then

  • Until completion, the junction is broadly closed to general traffic , with only emergency services, black cabs and TfL buses allowed through during the works phases.
  • Official updates and any change to the “spring 2026” target are being routed through TfL’s Gallows Corner project page and local council announcements, which both advise checking regularly for more precise dates as work progresses.

In short: there is still no exact day confirmed, but the current plan is a phased reopening starting spring 2026, assuming no further engineering or weather setbacks.
