Missed tunnel payment

HarryIb

I forgot to pay the Tyne Tunnel fee the other day, so there'll now be a late payment invoice arriving in the post I expect (I've paid now, but 11 hours too late). I made two journeys through the tunnel, there and back on the same day. Does anyone know if this counts as two missed payments, therefore two excess charges of £30, or is it one excess charge?

"you must pay by midnight the day after travel."

They are seperate journeys and both need to be paid for
