There's no shuttle buses tonight for Sam Fender... that's Saturday only.

There does seem to be a Shuttle for the Blaydon Races though as I've passed numerous Omnidekka's along Sandy Lane from Percy Main avoiding the LEZ by going all the way around.

It's more likely people are either doing the Blaydon Race or are at Sam Fender and when you rely on overtime from driver's only one thing will happen.
