Unique Structural Design and Construction Challenges for Al Bustan South Project in Qatar
Abstract
The Al Bustan Street South (ABS) Expressway Project features the longest dual
carriageway bridges in Qatar spanning 2.6 km each, with a minimum of four lanes
in each direction from south of Al Waab Street to south of Rayyan Road. These twin
mainline bridges carry the ABS Expressway forming a three-level interchange at Al
Waab Street and two-level crossings at Al Rasheeda Street and Snay Bu Hasa. The Al
Waab Interchange consists of multiple structures; namely, the mainline bridges at Level
+1, the West-South directional ramp at Level +2, and the East-North directional ramp at
Level +2. In addition, there are six other on/off ramp structures that tie into the mainline
bridges at various locations. While the current construction maintains Al Waab Street
at Level 0, in its ultimate configuration, Al Waab Street will contain an underpass at
Level -1, resulting in Level +4 interchange. This underpass due to its proximity to the
bridge supports requires unique design considering future constructability. The ABS
Expressway is part of the prestigious Sabah Al Ahmad Corridor which once constructed
will provide a separate north to south route from the Landmark Mall to Hamad
International Airport. The appearance of the bridges along the Sabah Al Ahmad Corridor
will contain aesthetically pleasing cladding attached to the parapets with artificial
green walls running down select piers and MSE Walls. This paper summarizes recent
developments in the design and build for the future underpass, which requires special
attention in the bridge design while also considering aesthetic features.
