Traffic will be switched to a section of newly-constructed carriageway between the Luncarty Junction and the new Stanley/Tullybelton Junction, overnight on Monday February 22, with a new traffic management arrangement in place from 6am on Tuesday February 23.
Road users are advised to take care on approach.
Prior to the switch, overnight temporary traffic signals will be required on the A9 on Monday February 22 between 7:30pm and 6am. This will allow the removal of temporary barriers, relocation of site access points and alteration of the traffic management layout to guide road users on to the new carriageway.
Road users are reminded that traffic will remain in single carriageway configuration following the traffic switch. Similarly, the current no-overtaking and 40mph speed restrictions remain in place and will continue to be enforced by Police Scotland and average speed cameras.
Following this traffic switch, road users will utilise the newly constructed A9 southbound carriageway for the entire 9.5 km journey through the project site.
In addition, overnight temporary traffic signals will be required at the northern extent of the project, between Coltrannie overbridge and Gelly overbridge, for up to five nights from Monday February 22 between 7:30pm and 6am each night, to remove temporary barriers.
The planned traffic management is weather-dependent and subject to change. Motorists can refer to the Traffic Scotland website or Twitter for live traffic up-dates.
