We went to the third one last year and I thought it was a farly tough one and quite meaty. I pretty sure the jump you describe was only used for the 2* they had there and the Advanced classes.
My trainer did the last Int at Tweseldown and yes, you did have to jump the footbridge. Didn't cause too many problems though. The sunken road and double of corners caused many more problems. I thought it looked quite meaty too.
