The final bridge beam at junction 28 of the M25 near Brentwood has been installed, as part of plans to create a new A12 anti-clockwise loop road.
National Highways has put in place six steel beams at Duckwood Bridge without any full road closures.
The team used a mega 1000-tonne crane for this operation, which was the largest beam lift for the project.
The finished beams, weighing 113 tonnes, were carefully craned onto concrete supports, known as abutments.

Zach Pepper, National Highways project manager, said: "Completing the final beam lift for the structures in the scheme is a significant milestone and a testament to the hard work of everyone on-site.
"This was completed all without the need for a full road closure, limiting the impact on the local community."
With the final beam in place, the team moves towards completing remaining structural concrete works by autumn 2024.
Duckwood Bridge measures 56 metres in length and 16 metres in width, and is set to be completed next year.
When finished, it will carry the new A12 anti-clockwise loop road, over the existing Weald Brook watercourse.

This bridge is a key part of improvements to upgrade junction 28 between the M25 and the A12.
Other improvements include changing the position of the A12 eastbound exit slip road and widening the M25 anti-clockwise carriageway at this junction.
