Guard rails and fencing are being added to Great Yarmouth's third river crossing ahead of its opening later this summer.
An official opening date of the Herring Bridge has yet to be announced.
But night images, captured by aerial pictures taken by Oliv3r Drone Photography, show the final stages of construction in the town's new £121m bridge.
Workers can be seen installing guard rails and fencing to the bridge's main deck as the leaves have drawn into position.
The load transfer platforms (directly next to the bridge leaves) have had their final concrete pours.
Road markings and traffic controls have been finished on either side of the bridge, and the bridge signals have been installed.
The third river crossing, which was named the Herring Bridge in March following an online poll, began construction in February 2021.
The new bridge will link the A47 at Harfrey’s roundabout to the port and the enterprise zone via South Denes Road on the other side of the River Yare.

Tim Ellis, Norfolk County Council's third river crossing project manager, said all operating systems will be tested under a 72-hour river possession in early August.
The River Yare has been closed to all navigation from August 7 to allow the installation of guard rails and fencing on the main bridge deck, together with the safe testing and commissioning of all bridge operating systems.
This river closure will last until 4pm on Thursday, August 10.
No vessel movements will be permitted within the construction area during this time.
Mr Ellis said: "We apologise for any inconvenience and thank you for your patience whilst this essential work is carried out."
Great Yarmouth MP Sir Brandon Lewis said the major infrastructural project could boost the town's case in gaining more support in dualling the A47 Acle Straight.
