Cable-stayed bridge on Sabah Al-Ahmad Corridor project

Qatar kicks off work on first cable-stayed bridge

DOHA, April 21, 2019

Qatar’s Public Works Authority (Ashghal) has started the construction of the first cable-stayed bridge in the country and the conversion of Haloul Roundabout into a two-level interchange on Sabah Al-Ahmad Corridor project.

The 1,200-m-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 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. – TradeArabia News Service
