The tunnel is 1.5 km long and sits 25 meters below ground level making it the longest and deepest bi-directional tunnel in Qatar. At this initial stage, 2 out of 4 lanes in each direction will be delivered, accommodating 8,000 vehicles per hour in each direction #Ashghal #Qatar pic.twitter.com/NUJkYBZTCx— هيئة الأشغال العامة (@AshghalQatar) January 12, 2019
Project Engineer Jumah Al Bader: the tunnel will reduce travel time between Bu Erayen and Lebday Streets and Al Luqta and Al Waab by up to 65 % due to the increased lane capacity and removal of the existing diversions and will cut traffic congestion on 22 February Street #Ashghal pic.twitter.com/8gRn5cCxjK— هيئة الأشغال العامة (@AshghalQatar) January 12, 2019
Project Engineer: Works of the new tunnel faced many challenges that were overcome. It was necessary to establish multiple diversions & two temporary intersections. Excavating 25m below ground level meant that project team had to manage extremely large quantities of groundwater pic.twitter.com/YiKzEOUq1r— هيئة الأشغال العامة (@AshghalQatar) January 12, 2019
The opening of the tunnel follows another series of milestones late 2018: two new underpasses at Al Mokafaha I/C and Khalid Bin Abdullah Al Attiyah I/C and a bridge at Khalid Bin Abdullah Al Attiyah I/C and a tunnel at Sheikh Khalid Bin Hamad Al Thani I/C #Ashghal pic.twitter.com/gngKwr2shQ— هيئة الأشغال العامة (@AshghalQatar) January 12, 2019
