A flyover linking the A12 and the A127 in Essex with east London is on track to fully reopen by the end of September after the completion of water infrastructure work, Transport for London (TfL) has said.

The Gallows Corner flyover was built in the 1970s as a temporary structure but has undergone major strengthening refurbishment over the years.

Essex & Suffolk Water (ESW) has now completed "complex work" to divert and replace a strategic water main - and a number of distribution mains - beneath the junction, and has now handed the site back to TfL.

The flyover closed in March last year but its reopening in April was pushed back, with progress marred by a series of delays.

The reopening follows the completion of final testing, cleaning and commissioning of the new water main, TfL said.

A final phase includes a full weekend closure and two overnight closures before it reopens to general traffic by the end of September, and speed and weight restrictions will be lifted later to allow larger vehicles through.

Scott Haxton, TfL's director of capital delivery Infrastructure, said: "We'd like to apologise to local residents, businesses and road users for the delays to these works and thank them for their patience while this essential project has been carried out."

"Essex & Suffolk Water has now completed its works and handed the site back to us, allowing us to move into the final phase of the project.

"We're working closely with our contractor, Costain, to complete the remaining resurfacing and reinstatement work as quickly and safely as possible."
