Traffic will be permanently shifted onto the lanes of the New Orbital Highway along a 2.5km stretch of the Temporary Truck Route, located 25km west of Doha to the south of Interchange No 24 on Salwa Road (See the map), according to an Ashghal statement.

It is being done to continue the construction of the fifth lane of both the directions of the main carriageway.
The proposed road change has been designed in co-ordination with the General Directorate of Traffic. It will be implemented and permanently maintained starting from Tuesday.

This realignment will be implemented in two phases over the next two weeks. During the two phases, the road users travelling on both directions will be shifted onto parallel roads and can continue their journey towards Salwa Road or Mesaieed as required.
The first phase will be implemented Tuesday and will include the complete closure of the eastbound lanes on the existing Temporary Truck Route (TTR), to be replaced with the the truck lanes of the New Orbital Highway.
The second phase will be implemented on December 17 and will include the complete closure of the westbound lanes on the existing Temporary Truck Route to be replaced with the truck lanes of the New Orbital Highway.
Ashghal has advised road users that it will need to reduce the number of lanes on this 2.5km section of the TTR from the existing three lanes to two permanent Orbital truck lanes in order to complete the required construction works.
The Public Works Authority will install road signs advising motorists of the road change. ‘Ashghal’ requests all road users to abide by the speed limit, which remains at 80 kph for this 2.5km section of the Orbital, and follow the road signs to ensure their safety.
