Major sections of a new road on the outskirts of Morpeth are being put in place.
Work started last week to deliver large units that will create the How Burn culvert on the Morpeth Northern Bypass.
The 6m by 3m units will eventually be put together to create a 6m by 6m tunnel on the site.
Six units were delivered to the site last Thursday, with lorries travelling through the town.
And motorists are being advised there may be further delays with six more units being delivered tomorrow (Friday), on April 19 and April 22.
A 500tonne crane will also be making its way through Morpeth to the site on April 18.
Overall, 64 units will be used to complete the 60m long culvert. Each one weights 26 tonnes.
Mark Denham, Carillion Plc agent at Morpeth Northern Bypass, said: “How Burn culvert is a major part of the Morpeth Northern Bypass, so as we ready ourselves to set these concrete sections in place next week [April 18], we’re marking a key milestone for the project.
“It has now been a year since works started on the project and, with culvert sections arriving throughout April, progress is right on track.
“The bypass will bring huge benefits to Morpeth and the wider south of Northumberland, so it’s great to see that these gigantic deliveries have really got the local community talking and getting excited about the project.”
