Police are planning to step up the presence of their mobile speed vans around Kettering to coincide with the improvement works to widen the A14.
Safer roads enforcement officer John Finden, who will be based in the town for up to 18 months, said Northamptonshire Police were anticipating extra traffic in the town as motorists try to avoid the A14 roadworks.
The works will include periods of full carriageway closures between Junctions 7 and 9.
He said: “We will be measuring the volume of traffic. Are people jumping off the A14, are they speeding through Kettering to get back on it?
“I will be working around the A14 and the surrounding areas – not just focused on the A14 itself.”
Mr Finden and colleague Matt O’Connell were speaking to the Telegraph in Gipsy Lane, Kettering, which is to be added to the force’s list of sites where they will station mobile speed cameras.
The road is an alternative route between Junctions 7 and 8 of the A14, and Mr O’Connell said: “There’s going to be some traffic that’s going to try and jump off, to try and cut around the roadworks.”
There are currently about 140 sites for mobile speed cameras in use across the county.
A relatively long stretch of straight road is required to ensure the vans are not a hazard to traffic.
