The Public Works Authority 'Ashghal' has started the construction of the first Cable-Stayed Bridge in Qatar and the conversion of Haloul Roundabout into a two-level interchange on Sabah Al-Ahmad Corridor project. The 1,200-meter long new bridge extends prior to Haloul Roundabout through Faleh Bin Nasser intersection in Salwa Road to provide free traffic flow between Hamad International Airport and the areas of Bu Hamour, Mesaimeer and Al Waab.

The new bridge will consist of four lanes in each direction to accommodate more than 16,000 vehicles per hour. Due to the length of the bridge, construction work will require the use of 854 precast concrete pieces, each weighing about 200 tons of reinforced concrete and 20 pylons and 16 piers to reach the highest point of the bridge to 30 metres high. Halul Roundabout will be revamped into a two-level interchange, which will include at-grade signalized intersection along with the free flow Cable-Stayed Bridge. With the completion, the signalized intersection will consist of (6) lanes in each direction, including two right turns to the left and one for U-turn.

The intersection will help the traffic in all directions to connect Sabah Al Ahmad Corridor to Halul Street and Salwa Road. It will serve Bu hamour and Al Mamoora and many vital facilities surrounding the Wholesale Market and commercial activities on Salwa Road. Engineer of the project Abdullah Al Naiemi said that Ashghal has already started construction of the first Cable-Stayed bridge in Qatar, which was designed in a unique way to provide a free traffic flow without the need to pass through roundabouts or light signals, especially that the bridge will pass over Halul intersection as well as Faleh Bin Nasser intersection on Salwa Road, which will ease the congestion in the vital area significantly.

He explained that the bridge over Faleh Bin Nasser intersection on Salwa Road will be without pylons at all for a distance of 150 meters, but there will be cables to bear the bridge, pointing out that the completion of the bridge will be the first quarter of 2021, as well as the completion of Halul Intersection works 2020. To facilitate the works, Ashghal announces a partial closure of Faleh Bin Nasser Intersection on Salwa Road, while maintaining traffic movement through Sabah Al Ahmad Corridor and right turns open, starting Thursday night of 18th April 2019 for 48 hours to enable construction works of the cable-stayed bridge on Sabah Al Ahmad Corridor. in the second stage, 'Ashghal announces a partial closure of Faleh Bin Nasser Interchange at-grade for traffic on Salwa Road, starting Sunday morning 21 April 2019 for 8 months to enable construction works of the bridge on Sabah Al Ahmad Corridor.

During this partial closure which is designed in coordination with the General Directorate of traffic, road users will be required to use alternative routes. Sabah Al Ahmad Corridor extends for approximately 25 kilometres from Hamad International Airport to Umm Lekhba Interchange (known as Landmark Interchange) on Doha Expressway. Its scope includes the upgrade of seven (7) main roads namely, E Ring, F Ring, Mesaimeer, Al Bustan, Bu Erayyen, Lebday and sections of Al Markhiya Street. In addition, Ashghal will enhance 12 kilometres of local and peripheral roads intersecting with the Corridor. The total road works of the project is approximately 37 kilometres.
