Middlesbrough is playing host to this year's BBC Radio 1 Big Weekend.
Tickets for the event have officially sold out, meaning thousands are expected to descend on Middlesbrough's Stewart Park.
The event, which takes place from Friday May 24 to Sunday May 26, will lead to some travel disruption. Here's what you need to know:
Driving to the Big Weekend
The advice from Middlesbrough Council is simple: don't drive there.
There are no onsite car parks, roads in the vicinity of the park will be either closed or have restrictions in place.
If you are being dropped off, the advice is to be somewhere at least 15 minutes away and proceed on foot to Stewart Park.
Marton train station is the closest to Stewart Park. A full list of services running over Saturday and Sunday can be found on Middlesbrough Council's website.
Depending on where you are travelling from there will be limited to no access to the surrounding roads around Stewart Park. There's a map with road diversion details on Middlesbrough Council's website.
The number of people expected at the This is Tomorrrow festival in Newcastle
Meanwhile Newcastle will also be hosting its own major festival. 'This is Tomorrow' takes place in Exhibition Park over the weekend with events on Friday, Saturday and Sunday.
Similarly to the advice for Big Weekend revellers the advice is to leave the car at home.
There will be no parking facilities at Exhibition Park and no drop-off spaces. If you are driving then the advice is to find one of Newcastle city centre's multi-storey car parks and park there.
The nearest train station is Newcastle Central. Travellers can get the Tyne and Wear Metro to take them from the station to Exhibition Park.
