Changes would be made to existing traffic patterns on the Temporary Truck Route after the opening of a 4km section of the New Orbital Highway, Ashghal announced on Tuesday.
The changes are being done to facilitate the construction of Khuwaiteem Interchange.
The proposed road change, which will occur approximately 50km south west of Doha, has been designed in co-ordination with the General Directorate of Traffic.
It will be implemented on September 7 and is expected to be in place until Khuwaiteem Interchange is opened for public early next year.
To enable the construction of the multi-level, free-flowing Khuwaiteem Interchange, Ashghal has advised that it will need to close the existing temporary junction between the New Orbital Highway and the road that extends from Hamad Port.
Motorists and truck drivers planning to travel to Salwa Road or Dukhan Highway will have two alternative routes to arrive at their destination.
Using the new 4km section of Orbital Highway, motorists travelling from Hamad Port to Salwa Road or Dukhan Highway are required to continue straight over the Hamad Port Interchange towards the New Orbital Highway.
After reaching the existing temporary junction, road users need to turn left towards Mesaieed and travel for a distance of 2.5km before making a U-turn at the first designated point and heading directly north on the New Orbital Highway towards Salwa Road and Dukhan Highway.
Using Hamad Port Road and G Ring Road, motorists travelling from Hamad Port to Salwa Road or Dukhan Highway can also use the recently opened Hamad Port Road and the G Ring Road to reach their destination.
Motorists and truck drivers who wish to use Hamad Port Road are advised to exit right onto Mesaieed Road towards Al Wakra. At the first roundabout, road users should turn left onto Hamad Port Road and travel straight towards Aba Seleel Interchange on the G Ring Road.
At Aba Seleel Interchange, road users are advised to follow signage and access the correct flyover to travel west on the G Ring Road towards the New Orbital Highway.
Ashghal has said it will increase the number of lanes on the new 4km section of the New Orbital Highway from two to three lanes to cater to the higher volume of traffic leaving Hamad Port each day.
Ashghal will install road signs advising motorists of the closure and has requested all road users to abide by the speed limit, which remains at 80 kph, and follow road signs to ensure their safety.
