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.
Tickets to Elton John's first performance in south Cumbria go on sale tomorrow morning, at 9am.
The singer will be performing hits like Candle in the Wind at the Westmorland County Showground on June the 14th.
Tickets will be sold by Ticketmaster.
Elton John will be performing live in concert in Cumbria next summer.
The singer and his band will be at the Westmorland County Showground in June as part of his European tour.
It will be the first time the star, who has sold more than 250 million records, has appeared live in the Lake District. He previously performed at Carlisle United's Brunton Park ground in June 2007.
