Motorists have been facing chaos at the Broughton roundabout over the past week as work on widening approaches has taken place.
Roadworks to ease congestion at the roundabout have been ongoing since June.
Last week and this week overnight closures have been in place to enable some of the work to be carried out.
Drivers using the notorious A6/M55 intersection last Thursday night encountered problems when a lane of traffic had to merge with another because of the introduction of a red cycle lane.
One motorist said: “It was very dangerous. Somebody is going to end up having an accident there. T he traffic somehow ended up in the cycle lane, so everyone was trying to then squeeze into the next lane as the two neighbouring lanes remained empty.”
Martin Galloway, head of network management, said: “The work to widen and add capacity to Broughton roundabout will reduce delays at one of the most congested points on Preston’s roads, and we’re sorry for the temporary delays while we put the changes in place.
“We’re currently carrying out works overnight to minimise inconvenience as far as we can, but while this is happening people may find the layout has changed in the morning, so I’d ask them to pay particular attention when driving through the works.”
On Monday, Tuesday and Wednesday of last week, the A6 at the roundabout, including all access onto and off the M55 at Junction 1, was closed to traffic..
And various approaches to the roundabout were closed last Friday and Monday and Tuesday of this week.
