Dovrà essere smontato e modificato il ponte mobile ideato dall'Ufficio federale delle strade (USTRA) per rendere meno invasivi i cantieri autostradali. Una struttura sperimentale, in uso, ancora per pochi giorni, sulla tratta solettese della A1. Il primo bilancio fornito dall'USTRA non è però del tutto incoraggiante.
Il ponte mobile non è riuscito ad evitare le code in concomitanza con i cantieri. "Il problema principale della struttura è quello legato alla rampa d'accesso, troppo stretta e troppo ripida soprattutto per i mezzi pesanti" spiega Richard Kocherhans ai microfoni della radio della Svizzera tedesca SRF. "La rampa dovrà essere quindi modificata in modo che tutti i veicoli riescano a circolare ad una velocità di 60 km/h".
L'esperimento di ponte mobile continuerà comunque, dopo le necessarie modifiche, il prossimo anno.
