Full-time security and CCTV cameras have had to be installed at a construction site near Rothbury as trespassers continue to try to access the site.
Work is ongoing on the B6344 to repair the Cragend landslip, which has resulted in the road being closed since Boxing Day 2012.
But despite fencing and the site being cordoned off, people are still trying to access it.
Posting on his Facebook page, Rothbury Coun Steven Bridgett said: “It is an unfortunate measure but the council and the private contractors working on the Cragend landslip have had to employ full-time on-site security and begin deploying CCTV cameras due to the high number of individuals entering the site and stealing fuel and machinery (It is believed to be travelling criminals).
“Could I also remind any of the many walkers and cyclists who still continue to enter what is, for all intents and purposes, a construction site; that this is not permitted in any way shape or form and for your own safety you will be escorted from the site.”
Work is well underway at the site with repairs to the actual road due to start soon.
Coun Bridgett said: “Obviously the council and private contractor are continuing to work to the schedule with the aim of having the road open next August and that has always been the plan.
“Walkers and cyclists are going into the site which could cause an issue.
“But now if people do decide to wander on they will be asked to leave and escorted off the site.
“They are getting on really well with the work. From what I understand the dewatering system is installed under the road and they are at the stage where they can start to rebuild the actual road.”
A spokesman for Northumberland County Council said: “We have checked with the contractors and established nothing has in fact been stolen from this site. However, like most construction sites of this nature, there is full-time security in place once work finishes for the day.”
Northumbria Police said there had been no reports to them of any thefts.
