In life, often, it is better to find a practical solution to a problem rather than enter into protracted and unnecesesary argument, contention and aggravation. I believe that there may well be a practical solution to the threat of the Mayor of La Linea to impose a toll on all cars leaving Gibraltar, despite that calling it a "Congestion Charge" is a travesty of reality and language.
A "Congestion Charge" has as its main objective the avoidance of congestion. This is not the aim of the La Linea Mayor. If it was then he would impose it as cars entered La Linea. He cannot because they enter on what is (we are told) a National Highway. What he plans is not a "Congestion Charge" but an "Extortion Charge". He wants to allow cars into Gibraltar, then, because there is no other way out, other than the frontier road into La Linea, he can extort a payment from each of those drivers trapped in Gibraltar thus enanbling each to return home or to their destination of origin. Sicilian Mafia tactics? ... maybe not ... I think that it beats anything that that Mafia could have thought of.
The solution? Well, if the Government of Spain is to be believed, in that they proclaim good intentions toward Gibraltar, both specifically on this issue and generally under the Cordoba Agreement and the Tripartite Process, then the solution is entirely in their hands. We have been told that the road to the frontier is a National Highway and not a La Linea ayuntamiento road. If that is so (and, as I believe the case to be, the frontier area comes, also, under the responsibility of the National Government) then all that needs to happen is that traffic is diverted away from the road controlled by the La Linea Ayuntamiento, on which they are undertaking preparatory roadworks in order to implement the toll. This is the road that is just beyond the exit of the frontier perimeter next to the La Linea frontier taxi stand.
This diversion can be achieved very easily by turning outbound traffic to the left, just beyond the Spanish Custom House and behind the Taxi Stand, rather than in front of it which puts traffic onto the La Linea Ayuntamiento road. This traffic will then join the National Highway that is used to access the entry into Gibraltar. Thus the La Linea Ayuntamiento cannot charge a toll as that road is not locally controlled. Those who want to contribute to the well being of La Linea, beyond all the help that Gibraltar already gives La Linea by employment and cross-border business, fro example Mr Reggie Norton and his supporters, can volunteer to go via the La Linea local road and pay the toll.
