Doha Expressway

Mesaimeer Bridge
As a part of the E-Ring road the Mesaimeer Bridge will serve as an elevated highway in order to relieve the existing road. The bridge will lift the majority of cars away from ground level and create a less trafficked area below the bridge. The challenge of this particular bridge was to have long and wide spans, while there was a demand for as much light below the bridge as possible in order to avoid the area being dark and unpleasant. This was solved by making the deck as slender as possible, using the extradosed concept to minimize the deck height and by making the edge as thin as possible while narrowing the lower part of the box. The deck became much lighter and more elegant.

The low pylons add a unique driving experience to the bridge. At night, the pylons will be perceived as beacons in the dark, and the underside with its dynamic light will be a visually intriguing place, for both locals as well as people passing by.  

Expressway Underpasses
The project concerned the design of six underpasses with a width varying from two to six lanes including portals and light concept. Our aim was to have a clean and simple shape that in a subtle, yet effective, way provides the users and the inhabitants with a unique and elegant underpass. For road users travelling at the designated design speed the trip is very short and the amount of detail perceivable is limited. Therefore, the main concept was to unfold the underpasses in a big scale with an easily readable and visually expressive solution.

The diamond shaped cladding panels will be hung on channels pre-cast in the retaining walls. The panels will be interchangeable, visually and aesthetically accommodating, and easily maintained – being cast in FRC with LED luminaires.

The concept will give the underpass itself and the matching wall treatment a significant expression, which will change during night and day. A sense of place will be established.

Pedestrian Bridges
In connection with the Doha expressway, DISSING+WEITLING was approached by Parsons Brinkerhoff in order to assist them in creating a design system for 14 pedestrian bridges located along the expressway. The bridges are covered due to the high temperatures, and the design system ensures that the bridges are seamlessly integrated at the different locations.

Several light designs and facade options were made in the design process with a strong focus on ensuring a high degree of recognizability, choice of material and building quality. DISSING+WEITLING prepared the concepts and tender in close collaboration with Parsons Brinkerhoff.
