Ashghal, the public works authority of Qatar, has opened a 1km uni-directional tunnel with one lane at Gharrafat Al Rayyan Interchange along Al Luqta Street as part of the Dukhan Highway East project to deliver direct free-flow connectivity from Gharrafat Al Rayyan to Doha.
According to project engineer Abdulla Qasim, the tunnel will have a capacity of up to 2,000 vehicles per hour and will reduce traffic congestion at Gharrafat Al Rayyan Interchange for commuters travelling from Gharrafat Al Rayyan to Doha.
He said that road users will also benefit from a 30% reduction in travel time from Gharrafat Al Rayyan to Doha.
Recently, the public works authority opened a 3km stretch of the main carriageway, providing four lanes in each direction along Al Luqta Street from west of Tilted Intersection until after Gharrfat Al Rayyan Interchange.
Besides the main carriageway, approximately 3km of parallel service roads with two lanes in each direction have been delivered, providing connectivity to key stakeholders, including the Qatar Foundation, Sidra Medical and Research Centre and Qatar National Convention Centre.
So far, Ashghal has completed 75% of construction work on Dukhan Highway East project, which is scheduled for completion in the third quarter of 2020.
The project will deliver 11.6km of dual carriageway with four lanes in each direction, replacing a three-lane way, besides seven interchanges, service roads, and auxiliary lanes along sections of the road and cycle, pedestrian and camel lane on the south side of Al luqta Street.
In 2018, Ashghal opened crucial sections of Khalifa Avenue Project, including a 3km road, as well as significant sections of the three-level Bani Hajer interchange.
The new interchange will accommodate nearly 1,500 vehicles per hour and will provide free-flow traffic movements. It is a key access to Dukhan Road, Al Luqta Street and Al Rayyan Road, Bani Hajer, Al Rayyan, Gharrafat Al Rayyan and Al Gharrafa.
The interchange consists of two bridges, two underpasses, three ramps (right turn exits) and two loops to provide connectivity in all directions.
After completion, the interchange will feature a 300m camel bridge, the first of its kind in Qatar, along with cycle and pedestrian lanes.
