Work to resurface Victoria Avenue is expected to last for ten weeks.
The road will be open for morning rush-hour traffic but there will be restrictions for traffic in the evening, when the westbound carriageway will be fully open but eastbound traffic will have a single lane.
During the evenings, westbound traffic will be restricted, while eastbound vehicles will be diverted at the Bel Royal bus cross-over onto the Inner Road as far as Rue du Galet.
Transport Minister Guy de Faye said that Victoria Avenue was in need of resurfacing.
