First Cable-Stayed Bridge in Qatar: Largest intersection and longest bridge, Sabah Corridor to reduce north-south travel time by 70%

* The Sabah Al Ahmad Corridor project is to be complete in 2021 

* The road, the first in Qatar to be called a Corridor, will have the first Cable-Stayed Bridge in Qatar 

* The road will also have the largest intersection, longest bridge, deepest and longest bi-directional tunnel 

* The Corridor will provide access to more than 25 residential areas and facilitate access to five 2022 FIFA World Cup stadiums

The new Corridor will be a vital alternative and parallel route that will serve thousands of daily commuters from the north to the south of Doha

The Sabah Al Ahmad Corridor project, once completed in 2021, will significantly contribute to relieve the traffic congestion on Doha Expressway in particular, 22 February Street, Dr Saad bin Ahmad al-Muhannadi, president of the Public Works Authority, Ashghal, said on Sunday.

The new Corridor will be a vital alternative and parallel route that will serve thousands of daily commuters from the north to the south of Doha.

People travelling from Hamad International Airport will be able to reach Umm Lekhba Intersection in approximately 18 minutes compared to the current 50 minutes via Doha Expressway and 22 February Street reducing traffic time by 70%.

The new Corridor will also form a vital link between the north and the south of Doha through Al Watiyyat Interchange, at F-Ring Road, which will constitute a key point to accommodate traffic to both Sabah Al Ahmad Corridor and Doha Expressway. This interchange will also create a vital connection between Doha Expressway and Southern Part of Doha Express Highway (Al Wakrah Bypass) as well as to Mesaieed Road further south.

The current road layout holds up to three lanes in each direction, which will be upgraded to between four and five lanes in each direction. This expansion will accommodate approximately 20,000 vehicles per hour in both directions on the Corridor while Doha Expressway currently accommodates 12,000 vehicles per hour, which will significantly improve traffic movements in the surrounding areas.

The project will convert all roundabouts to more efficient and safer signalised junctions as well as build and upgrade 17 interchanges. These interchanges will deliver 32 bridges and 12 vehicular underpasses to enhance connectivity and provide smooth traffic movements in addition to 12 pedestrian bridges. A total of 65km of pedestrian and cycle paths along with 1.5mn sqm of landscaping will also be delivered as part of the project’s scope of works.

The Ashghal president pointed out that the Corridor project launched in 2018, includes four contracts, which will upgrade E-Ring Road, F-Ring Road, Mesaimeer Road, Al Bustan Street South and Al Bustan Street North. He added: “Sabah Al Ahmad Corridor will facilitate access to five of the 2022 FIFA World Cup stadiums -- Ras Bu Abboud, Al Thumama, Al Wakrah, Khalifa International and Qatar Foundation Stadiums."

Overview of Sabah Al Ahmad Corridor

Sabah Al Ahmad Corridor will extend for approximately 25km from Hamad International Airport to Umm Lekhba Interchange (known as Landmark Interchange) on Doha Expressway. Its scope includes the upgrade of seven main roads namely, E-Ring, F-Ring, Mesaimeer, Al Bustan, Bu Erayyen, Lebday and sections of Al Markhiya Street. In addition, Ashghal will enhance 12km of local and peripheral roads intersecting with the Corridor. The total road works of the project is approximately 37km.

First cable-stayed bridge in Qatar

Sabah Al Ahmed Corridor includes the first cable-stayed bridge in Qatar with a length of 1,200m. It extends from Mesaimeer Road to Al Bustan Street and crosses over Halul Intersection on Mesaimeer Road and Faleh Bin Nasser Intersection on Salwa Road.

Longest bridge

The Corridor will be the home to the longest flyover in the country, which spans 2.6km extending from Al Bustan Street to Bu Erayyen Street and crossing over Al Waab Street and Rasheeda Street.

Largest interchange

Sabah Al Ahmad Corridor will include the largest interchange in Qatar. The impressively complex Umm Lekhba (Landmark) Interchange has nine bridges providing a free traffic flow in all directions highlighting its significance as a key access point on Doha Expressway for local residential areas and malls.

Longest and deepest bi-directional tunnel

The project consists of the recently opened Al Rayyan Road, which is the longest and deepest bi-directional tunnel in Qatar. It sits 25m below ground level and extends for 2.1km connecting Bu Erayyen Street and Lebday Street.

Residential areas and main Roads

The new Corridor is a major link facilitating connections to 15 main roads namely Al Wakrah Road, Ras Bu Abboud Road, E-Ring Road, F-Ring Road, Industrial Road, Salwa Road, Al Rayyan Road, Al Waab Street, Al Luqta Street, Al Markhiya Street, Doha Highway and Khalifa Avenue.

World Cup stadiums

Sabah Al Ahmad Corridor will facilitate access to most of the World Cup FIFA 2022 stadiums including Ras Bu Abboud, Al Thumama, Al Wakrah, Khalifa International and Qatar Foundation Stadiums.

Qatar Rail

The Corridor provides easy access to some of Doha Metro stations such as the Economic Zone, Al Waab and Old Rayyan.

Drive through Sabah Al Ahmad Corridor project

Once completed, road users coming from Hamad International Airport and southern Doha and heading north will be able to use the new Corridor via F-Ring Road then continue on the existing Mesaimeer flyover to use the new 900m bridge crossing over Al Shehaimiya Interchange (formerly known as Bu Hamour Interchange). The new cable-stayed Bridge will allow road users to drive towards the north avoiding Halul Intersection and Faleh Bin Nasser Intersection on Salwa Road to smoothly reach Al Bustan Street. From there, road users will be able to continue their journey using the 2.6km bridge. This will allow them to avoid the Snay Bu Hasa Intersection and Al Waab Intersection as well as Lekhwiya Roundabout, which will be converted to a signalised junction. At this stage, road users would have reached Bu Erayyen Street where they will be able to drive through the recently opened tunnel at Lebday Interchange in Al Rayyan, which connects to Lebday Street. Two additional bridges will deliver a free traffic flow to alleviate the traffic at Mekkah and Al Luqta Intersections and deliver connectivity to Thani Bin Jassim tunnel to continue their journey to the north, road users will be able to drive through Al Markhiya Street in Al Gharrafa and reach Umm Lekhba Interchange (known as Landmark Interchange).

The Corridor project is composed of four contracts: E-Ring and F-Ring Road Upgrade, Mesaimeer Road Upgrade, Al Bustan Street South Upgrade and Al Bustan Street North which will deliver new interchanges and connections:

1.    Contract One – E-Ring & F-Ring Road Upgrade Project

The new interchange will facilitate new paths to the stadium goers where it consists of two bridges and six pedestrian and cycle underpasses that will provide an easy and safe journey to the stadiums.

Formerly known Khamees Al Obaidly Interchange will be replaced by another three-level interchange composed of three levels , consisting two bridges and nine vehicle underpasses to form a strategic free flow connection between Rawdat Al Khail Street, Industrial Area Road in both directions and E-Ring Road on the southern part of Doha Expressway.

Road users can also use tunnels that provide free traffic flow between the southern part of the Doha Expressway, as well as the E-Ring and F-Ring Road, Rawda Al Khail Street and Industrial Area Road.

Upon completion, this interchange will allow road users to avoid the traffic congestion on the surrounding roads to facilitate access to Nuaija, Al Mamoura, Al Thumama and Industrial areas.

The E-Ring and F-Ring Road upgrade project will improve access to economic and public facilities such as Hamad International Airport and the Industrial Area among others.
