I do not blame commuters for using that tunnel and certainly not for the desire to use it. However, I do not wish them to do it. I remind the Deputy that the purpose of the tunnel is to get HGVs to the port on time, to keep traffic out of the port at peak times and to keep traffic out of the city at those times. This tunnel is of great assistance to trade and traffic control. We must accept that they are avoiding it because of congestion in the city and elsewhere. This is just part of the bigger problem which we are addressing as a matter of urgency. It is my wish and hope - it is not a vain hope - that those commuters who are using that tunnel or who are finding it too expensive to do so will soon be moving to a new form of public transport - a change of modal transport that is also cheaper.
