Doha Expressway: Sensitive and Safe Solutions for an Aggressive Construction Program

In preparation for the 15 Asian Games to be held in December 2006, the State of Qatar is implementing an extremely aggressive program to upgrade its roadway infrastructure. Critical to this will be the construction of the Doha Expressway, which will be Qatar’s first urban freeway. Rather than constructing this freeway network on reserved and undeveloped corridors, it will instead be upgrades of existing primary arterials. Due to the urban locations and the need to maintain existing access points, a network of parallel one-way frontage roads will also be constructed. Some of the Doha Expressway’s corridors, which are as narrow as 40m wide, will be extremely confined. Compounding the challenge is the Emir’s mandate that all urban interchanges be depressed, which necessitates the use of retaining walls and cantilever structures at many of the depressed urban interchanges. Finally, the existing corridors also convey major utility lines, which must be diverted parallel to and, in confined locations, under the frontage roads. Constructing the freeway network and upgrading the other major arterials within Doha is a challenge in itself. Due to the short schedule, many of the upgrades will need to be constructed simultaneously. This will require creative solutions and the patience of the general public because arterials that normally would provide relief during construction, will simultaneously be under construction. Furthermore, maintaining traffic through the narrow urban corridor during the depressed interchange construction will be a challenge and require extremely ambitious construction staging. Doha will have to resolve the challenge of not only upgrading their facility in line with their December 2006 goal, but also maintain day-to-day traffic during the construction phase without paralyzing their city. The staging and detour program must not only be effective, but it must be practical and sensitive to the residential neighborhood as well as safe to motorists and the community.
