The bridge is 6' in width and can only accommodate one-way traffic. With increased play at the course and much heavier use of the practice range, the bridge has become a bottleneck. ... He suggested a second 6' bridge be placed adjacent to the existing bridge and each bridge. This option would be less expensive and still be sufficient to eliminate the bottleneck. 2, record 1, English, - one%2Dway%20traffic

[...] Dans son interpellation cosignée par 75 parlementaires, Maspoli fait référence aux bouchons régulièrement enregistrés au début et à la fin des vacances d’été et d’automne, ainsi qu'à Pâques et à Pentecôte. Les bouchons pourraient être réduits en introduisant la circulation à sens unique sur les deux pistes de roulement. Le Conseil fédéral estime que des essais de circulation à sens unique pourraient tout à fait être tentés dans le tunnel routier du Gothard et sur la route du col, mais que ces essais pourraient être onéreux. 5, record 1, French, - circulation%20%C3%A0%20sens%20unique

Safety is to be improved at the Homer Tunnel ... . There is only enough room for one bus at a time, the tunnel is not lit and there is no emergency phone within the tunnel itself. Sunday's fire, although an unusual incident, is now raising wider issues for Transit including whether to make the tunnel two way. But tour operators say traffic flow was not to blame. David Kennedy of Destination Queenstown says: "The issue was a bizarre freak incident. A bus caught fire in the tunnel and whether it was a one way tunnel or two way tunnel would have been irrelevant, I think." 1, record 2, English, - two%20way%20tunnel

Selon la nature du terrain, on optera pour un tunnel à double sens(dépassement utilisant la piste centrale) ou deux tunnels séparés chacun à sens unique(dépassement plus difficile, vu l'étroitesse de la chaussée : 6 m). 2, record 2, French, - tunnel%20%C3%A0%20double%20sens

D’autres aspects, tels la sécurité et l’entretien, doivent également être discutés en corrélation avec une seconde galerie. Il va sans dire qu’un tunnel pour chaque sens de circulation est plus sûr qu’un seul tunnel à double sens. C’est ainsi que le nombre d’accidents recensés au tunnel du Seelisberg est inférieur de moitié à celui enregistré au tunnel du Gothard. Il n’empêche : l’actuel tunnel routier du Gothard est, selon l’OFROU [Office fédéral des routes], l’un des tunnels routiers les plus sûrs d’Europe. 3, record 2, French, - tunnel%20%C3%A0%20double%20sens

Much like the Alaska Marine Highway System, a staging area will be used at both ends of the tunnel for vehicles to line up for the next change of direction of travel. Since this is a one way tunnel, vehicles will have to wait their turn to go through the tunnel. In general, only a 15 minute period will be used for cars in one direction and then the direction of travel will be reversed. 4, record 3, English, - one%20way%20tunnel
