A specialist robot has been used to paint the white lines on the newest stretch of the A14 in Cambridgeshire.
The machine uses positioning technology to dictate where road markings should be put done, replacing a job previously done manually.
Highways England say it saves time and is also safer for their workers.
Two thirds of the A14 project is now complete, following the opening of the 12-mile Huntingdon bypass in December 2019.
The final stretch, between Swavesey and Milton, is expected to open in December 2020.
