Poole Gravel Hill traffic light plan opposed
More than 1,000 people have signed a petition to save a roundabout in Poole.
The roundabout on the A349 at the junction of Gravel Hill and Dunyeats Road is due to be replaced with traffic lights.
Campaigners say the proposed £4.3m scheme is "unnecessary and a waste of money."
Poole Borough Council said the eight-month long works, due to start in July, were needed to stabilise an embankment which is "at risk of failing".
The authority said installing the lights would improve traffic flow and also allow a crossing to be installed.
Gravel Hill, which links the A31 to Poole town centre, will be closed entirely to all traffic for three months during the work.
The council said £3.9m for the works had been funded from the Dorset Local Enterprise Partnership, the remainder by Poole Council.
