A Lancaster cyclist has raised concerns about the safety of part of the A6 after it underwent resurfacing.
The road between Lancaster University and junction 33 of the M6 was resurfaced last weekend using loose chippings, which have piled at the side of the road in a deep rut.
And one cyclist has said the new surface is a danger for bikers.
“The chips are flying up when cars drive past,” he said. “All the loose gravel has collected at the side of the road and it’s several inches deep where we have to cycle.
“Lancaster is trying to promote cycling as an alternative to using your car and then they do something like this.”
A Lancashire County Council spokesman said: “The surface dressing recently carried out on the A6 is a treatment using tar and stone chippings to prolong the life of the road by making it waterproof. This helps to prevent potholes appearing and is a much more cost-effective way of keeping the road in good condition than waiting until it needs to be fully resurfaced.
“The chippings are embedded into the tar using a roller, but the nature of the work means that some loose chippings are left initially, and we revisit the site periodically to sweep them.
“We put signs up to alert people to the loose chippings and would advise cyclists to proceed with caution where roads have been newly surface-dressed.”
