Both Vale Road and Le Val des Terres are now closed for three months and one month respectively.
It appeared that the motorists most affected by the roadworks were those who were travelling through Delancey Lane in the Vale, with reported tailbacks to the Saltpans.
Traffic and Highway Services said the congestion along the lane was caused by a number of drivers ‘failing to follow alternative diversion routes’, such as Braye Road and the Coutanchez.
It advised those drivers who sought to bypass Vale Road through the Delancey road network not to use the route.
