Longest Tunnel In Qatar

The Public Works Authority ‘Ashghal’ has opened the longest and deepest bidirectional tunnel in Qatar for beneficial use as part of the construction of the Al Rayyan Road Upgrade Project Phase 2. The tunnel forms part of the newly upgraded 2.1 kilometre stretch between Bu Erayen and Lebday Street. According to the press release published by Ashghal, the event was attended by Eng. Yousef Al Emadi, Manager of Highway Projects Department, Brigadier General Mohammed Maarafiya, Manager of MOI Traffic Safety Department, and a number of officials and project engineers.

The new tunnel is a major link between Bu Erayen and Lebday Street Streets spanning the interchange known as Al Mokafaha and Lebday Interchange.

The tunnel is 1.5 kilometers long. It sits 25 meters below ground level making it the longest and deepest bi-directional tunnel in Qatar. At this initial stage, two (2) out of four (4) lanes in each direction will be delivered, accommodating 8,000 vehicles per hour in each direction.

The tunnel forms part of the complex three (3) level interchange known as Al Mokafaha interchange. At-grade there is signalised junction which facilitates traffic movements in all directions including Al Waab, Bani Hajer and Doha. Beneath this is an underpass which allows road users to travel seamlessly between Doha and Bani Hajer. The tunnel is beneath the underpass both of which replace the old roundabout.

New Openings:

The Project Manager Mr. Jumah Al Bader confirmed that the newly opened section of road and tunnel will reduce travel time between Bu Erayen and Lebday Street and Al Luqta and Al Waab by up to 65 % particularly due to the increased lane capacity and removal of the existing diversions and will reduce traffic congestion on 22 February street.

Challenges

He added that the construction of the new tunnel faced many challenges that were overcome. For instance, it was necessary to establish multiple traffic diversions and the construction of two temporary signalised intersections to facilitate the progress of works. Excavating 25 metres below ground level meant that the project team had to manage extremely large quantities of groundwater. He explained that the tunnel is fitted with all the safety and security facilities and that a dedicated building was constructed to serve as the central control room for monitoring and controlling all operating system. This built-in system will allow the safe operation of the tunnel.

Previous openings

The opening of the tunnel follows another series of openings achieved by Ashghal towards the end of 2018 as follows: the partial opening of two new underpasses at the interchange known as Al Mokafaha and Khalid Bin Abdullah Al Attiyah Interchange and the partial opening of a new bridge at Khalid Bin Abdullah Al Attiyah Interchange and a new tunnel at Sheikh Khalid Bin Hamad Al Thani Interchange.
