Darlington Upgrade Project – Lowered motorway traffic switch: 19-20 December

Wednesday, 18 December 2019

As part of the Darlington Upgrade Project, another stage of the new motorway is opening to traffic, providing improved connectivity throughout the project.

From 8pm, Thursday 19 until 6am, Friday, 20 December, the following traffic restrictions will apply:

• The Southern Expressway (lowered motorway) will be closed to traffic in both directions. Motorists will be required to use the Main South Road surface roads.
• Intermittent lane closures and speed restrictions will be in place on the Ayliffes Road bridge.

Following the switch, the following traffic arrangements will be in place:

From Southern Expressway to Ayliffes via motorway northbound  

• Northbound Southern Expressway traffic travelling to Ayliffes Road will need to position themselves in the left lane of the Southern Expressway (motorway) to exit to the Ayliffes Road bridge.

The lowered motorway will now be named Southern Expressway with signage that refers to the “Southern Expressway” installed as part of this switch.

Please plan ahead, allow extra travel time, take extra care when workers are on site and observe speed and lane restrictions when travelling through the area.
