New tunnel opens on Lusail Expressway at Al Gassar Interchange

The Public Works Authority (Ashghal) has opened a new 750m-long tunnel at Al Gassar Interchange on Lusail Expressway.

The new tunnel will provide free-flowing traffic from Lusail and The Pearl-Qatar towards Katara-the Cultural Village and surrounding hotels and facilities as the passage offers a direct connection between Lusail Expressway and the Al Khafji Street extension.The opening took place in the presence of Ashghal Highway Department manager Youssef al-Emadi, Katara general manager Dr Khalid bin Ibrahim al-Sulaiti, Central Municipal Council (CMC) member Jassim al-Malki along with a number of Ashghal officials and project engineers. The tunnel incorporates two one-way lanes to accommodate more than 3,500 vehicles per hour along with a hard shoulder to prevent any traffic disruptions inside the underground passage, Ashghal has said in a statement.The opening is among a series of milestones achieved on Lusail Expressway, which was opened to traffic in December 2017 to enhance traffic mobility in the surrounding areas. The new road led to a reduction in journey time by over 70% compared to the old road, Ashghal stressed.Major overhaul and expansion works have taken place on the previous road, which involved two lanes in each direction to cater to around 3,500 vehicles per hour. The road capacity was more than doubled to approximately 8,000 vehicles per hour after increasing the number of lanes to four tracks in each direction and up to six and eight lanes in some sections of the new highway. Five roundabouts were also converted into three multi-level interchanges to provide free-flowing traffic in all directions.On this occasion, project engineer Abdullah Qassim said the new tunnel is part of the four-level Al Gassar Interchange that consists of five tunnels and a flyover, linking traffic between Lusail Expressway and Al Khafji Street.Continuing the achievements of Ashghal on Lusail Expressway, he said the new tunnel will reduce the transit time as motorists travelling from Lusail towards Katara and nearby hotels will have direct access now and no longer require any diversions. “Before the opening of the underground passage, road users travelling from The Pearl-Qatar and Legtaifiya, for instance, to Katara and neighbouring hotels would have turned right at Al Gassar Interchange onto Al Khafji Street to Qatar University Street, then do a U-turn or continue driving to the 5/6 Interchange and then do a U-turn,” he explained “The murals that Katara Tunnel is characterised by are among the architectural and artistic elements inspired by the Qatari pearl diving marine heritage. These patterns, which are derived from the fisherman’s net with its blue colour, suggest that they are ripples of a diver under the water, and at the end of the tunnel the ripples fade away in the horizon. The lighting poles were also chosen in a new way to add an aesthetic dimension in line with the overall design,” Qassim said.Lusail Expressway is one of the key projects of the Expressway Programme that the Public Works Authority is implementing. It is located in a vital area that connects Doha with Lusail City, and covers many public destinations such as The Pearl-Qatar in the north, via Katara and the Diplomatic Area, and a big number of residential areas, hotels, malls and other facilities. The project work area stretches over 5.5km from Lusail City in the north to the West Bay area in the south. The project works include three main multi-level interchanges, which are the Pearl Interchange, Al Gassar Interchange and 5/6 Interchange, in addition to two bridges over the South and North Canal crossings near The Pearl-Qatar and Lusail City. The design also focuses on enhancing traffic safety for pedestrians and providing a healthy lifestyle by building a total of 13km of pedestrian and cycling paths, in addition to a big number of feeder service roads to connect different destinations with the expressway.One of the most prominent architectural monuments in Doha, the arches of the 5/6 Interchange - which was launched on December 16, 2017 – make it an icon of creativity and engineering achievement.

The 5/6 Interchange arches are the biggest and tallest monument in Qatar with a height of 100m and width of 147m, and weighing more than 9,300 tonnes of steel.The vast excavation and execution works on the multi-level tunnels and bridges of the Lusail Expressway project, as well as the construction of two marine bridges, was completely executed without interrupting traffic, Ashghal said. This is in addition to excavation works that took place at a depth of 30m below ground surface along 6km, for integrated infrastructure works to allow for electricity and drainage networks, and allow for maintenance works without the need for more excavation in the future. This is in addition to building an underground Metro tunnel that will cross under a marine bridge.The design of Lusail Expressway is an integrated system that provides traffic flow and connects Doha with West Bay to enhance access to the important destinations and landmarks that the area covers. Lusail Expressway stretches parallel to the important landmarks and destinations on Doha’s coast, and with its location that includes the most important attractions in the country, “it will become a ‘painting’ and a road that is characterised by a unique view inspired by the old Qatari heritage in a contemporary vision”, the statement notes.VoicesRoad users have expressed happiness at the accomplishment of Lusail Expressway, stressing that the new road has largely created better traffic, especially that it connects many key areas and business, tourist and entertainment facilities.
