Plans to replace a roundabout between Fleetwood and the M55 with traffic lights have been put on hold after concerns were raised by local people.
Work on the revamp at the A585 between Amounderness Way and the Norcross roundabout was set to begin on 28 February and last for four months.
Tim Ashton, Lancashire County Council's cabinet member for transport, criticised the lack of consultation.
The Highways Agency has said it will carry out a review into the scheme.
Mr Ashton had said the new layout, which affects traffic to and from the M55, was "not the right use of public money".
"[The Highways Agency] should listen to local people, go away and think about it and perhaps see if the money could be spent better elsewhere," he said.
Matt Sweeting, the Highways Agency's North West Regional Performance Manager, said: "Our contractors informed interested parties, including local authorities and MPs, last autumn about our proposed works at Norcross Junction.
"We want to reduce queues on to the roundabout at peak times and provide safer crossings for pedestrians and cyclists.
"However, we recognise the local concerns that have been raised and will now look again at the proposals for this junction."
