Public Works Authority (Ashghal) opened four major interchanges (51, 62, 68 & 84) on the Salwa International Highway. The Umm-al-Jamajim Interchange (No 51) serves the sand quarries and plant directly, easing round tour in four directions. The Kar’ana Interchange (No 62) serves Karana area directly in addition to the army camp, the estuary of sewage plants and the Construction Materials Plant under implementation, facilitating round tour in the four directions.  The Sudanthil Interchange (No 68) serves bypass movement in four directions as it also serves the residents of Amiriya area. It also connects Salwa Road with the new Dukhan Highway. Whereas the Interchange No (84) serves bypass movement within the intersection as it will also serve future projects.
On the other hand, traffic on Salwa Road will be diverted temporarily through the service roads, starting from the Miknees Interchange up to Bu Nakhla Township towards Doha city, in order to complete works of the last phase of the Salwa Road Project.
Salwa International Highway extends from the Industrial Area to Abu Samra on the Saudi border along 81 kilometers and contains four-lane dual carriageway with 10 interchanges, with international specifications of expressway. The median along the highway is 20 meters wide with beautification and streetlights. In addition, there is adequate number of weighbridges at important junctions.
The project also includes emergency parking areas, parallel service roads, infrastructure lines of communication, drainage, water etc, in addition to the crossings to protect the pipelines of oil and gas to facilitate maintenance of these pipelines without the need for road closure or cuttings. The highway is equipped with all means of traffic safety and forestry at intersections and lightings.
It is noteworthy that the full completion of the project will accelerate the flow of traffic between Doha and Abu Samra, contributing directly to the growth of business and economy, as well as other aspects that are useful and beneficial to the citizens of Qatar, the GCC and the Arab world in general.
