Design and Supervision of R902 Improvements of Sheikh Mohamed Bin Zayed Road, Stage 2
CDM Smith was commissioned by Dubai’s Roads and Transport Authority to design and supervise the major widening of Sheikh Mohamed Bin Zayed Road (formerly Emirates Road), Stage 2, which is located in the eastern part of Dubai metropolitan area and running in the north-south direction. The project, which was split into several phases, started at the Arabian Ranches Interchange to the north up to the beginning of Sheikh Mohamed Bin Rashid Road at the Dubai / Abu Dhabi border to the south. The alignment runs parallel to Sheikh Zayed Road (E11) in the west and Emirates Road (formerly Dubai Outer Bypass Road) in the east.
The improvements involved the widening of the existing highway along an approximate length of 33 km. The widening took place on the median side and comprised the construction of three additional lanes in each direction to eventually form a 12-lane divided highway with inner and outer shoulders, separated by a double-faced concrete barrier. The project scope also included the development of the extension of the Academic City Road that runs parallel to Sheikh Mohammed Bin Zayed Road for an approximate length of 24 km. The total project length was divided into different contracts.
Phase 1 involved the widening of the existing road with an approximate length of 7 km, construction of a grade-separated interchange at the intersection of Hessa Street, and upgrading of Al Houd Roundabout, which involved the construction of the three-lane directional link serving the traffic from Jabal Ali port along Al Yalayis Street towards Dubai and the Northern Emirates. This phase was completed in 2012.
Phase 2 involved the widening of the existing road with an approximate length of 13 km. The widening commenced at the end of the previous phase up to the existing Al Maktoum Airport Street Roundabout intersection. This phase also involved the second stage of the upgrade of the Al Houd Roundabout to a full cloverleaf interchange. This phase was completed in 2016.
The project contained a number of obstacles and existing critical services. Working closely with key stakeholders ensured successful delivery on schedule and within budget.
Phase 3 will involve the upgrading of the remaining part of Sheikh Mohammed Bin Zayed Road with an approximate length of 10 km, along with the development of several grade-separated interchanges to replace the existing roundabouts. This stage is expected to be implemented in the near future.
Phase 4 involved the extension of the Academic City Road project located in the eastern part of Dubai urban area. The road corridor is bonded between Sheikh Mohammed Bin Zayed Road to the west and Emirates Road to the east running north-south direction with an approximate length of 23 km bounded by Dubai-Al Ain Road (Academic City Interchange) and Al Yalayis Street and is running parallel to Dubai-Sharjah gas pipeline corridor. The scope of work involved the construction of a dual carriageway of four lanes per direction with a total length of 23 km along with the upgrade of the existing road from dual two lanes per direction to dual four lanes per direction with a total length of 10 km. This phase was developed under several sub-phases. The phases that were completed or are currently being implemented are shown below.
Phase 4A. This phase was divided into two sections: Section 1 involved the construction of Hessa Street, a dual carriageway road connecting the existing road segment of Remram’s access on Emirates road to the existing Dubai Motor/Sports City roundabout junction (constructed under R902/1) while converting it into a traffic signal. The project made provision to the construction of the intersection with Academic City Road and future upgrades without any interruption to traffic flow. Section 2 involved the construction of a dual carriageway road connecting the “Villa Project” to Emirates road while providing a future extension to the proposed Academic road extension.
Phase 4B. This phase will involve the construction of the interim design of the extension of Academic City Road from Al Yalayis Street up to Dubai-Al Ain Road for a length of 23 km. In this phase, a dual carriageway road shall be developed, which will consist of four lanes per direction, along with the construction of a crossing bridge crossing over Latifa Bint Hamdan Street. It will also involve the development of a temporary roundabout at the intersection of Al Qudra Street and the stage construction of a signalized junction at the intersection of Hessa Street. The last two junctions will be upgraded in the upcoming stage of Phase 4C.
The works also included the provision of street lighting services to the proposed roadway facilities, crossing ducts for different utilities, and the relocation and/or protection of existing services affected by the proposed highway scheme based on coordination and approval of the respective utility authorities. CDM Smith's services included preliminary study, preliminary and final design, and construction supervision.
