A traffic plan is in place around Leeds to try to ease congestion around the city before a forthcoming festival.
Leeds Festival begins on Friday and thousands of people are expected to arrive at Bramham Park.
Part of the A64 York Road is closed to traffic until Friday morning in a bid to ease congestion.
Traffic for the festival is being directed onto the A1(M) coming off at junction 45 and onto West Woods Road and Paradise Way.
An additional route is also available on Thursday as this is expected to be the busiest day for festival-goers.
Police said drivers could use the A1 to junction 44 and travel towards Leeds using both lanes on a one-way system.
As a result, the A64 will be closed to all traffic travelling eastbound from the Fox and Grapes pub until 0500 BST on Friday.
Motorists are advised to avoid the area on Thursday, particularly around the junction where the A64 meets the A1.
Police said a number of other temporary road restrictions were in place in and around the city.
A West Yorkshire Police spokesman said: "Drivers are strongly advised to use alternative routes wherever possible and allow plenty of extra time for their journeys."
