Changes to speed limits, traffic flow and parking arrangements are introduced from 1 October.
Speed limits will be increased from 25 to 35 mph until the end of May from the Martello Tower at Vazon to Fort Houmet access road and also from the Imperial Hotel to La Route du Coudre.
The summer one-way restriction on Petit Bot Road and La Rue des Pages between the hours of 1000 and 1900 has also been removed and two-way access will remain in place until 31 May.
There are a number of changes to parking too with approximately six spaces on the landward side opposite Credit Suisse changing from two-hour to 10-hour parking.
In addition the 40 parking spaces near the slipway signed as two–hour parking for the cruise liner season have reverted to 10-hour parking until spring next year.
At La Valette the seaward side of the road between Horseshoe Pool and the Ladies Bathing Pool will change from two-hour to 10-hour parking.
