Cumbria Police are advising motorists to allow extra time and follow the correct road signs when travelling to Elton John's concert this evening.
The singer is performing at this year's Westmorland County Show and thousands of tickets have been sold.
Traffic signs will take those travelling from the south along the A6 to Milnthorpe, and right at the crossroads.
Police say for those coming from the north, the best route is to turn off the Brettargh Holt roundabout and head to Milnthorpe, turning left at the crossroads in the centre of the town.
The traffic lights at the crossroads will be manually operated to ease traffic.
