SYSTRA Arabia is assisting with the Northern Obhur Road project in Jeddah, including its iconic road bridge over Obhur Creek encompassing 8 traffic lanes and two metro lanes. The construction of this new bridge is part of the expansion of Jeddah, the second largest city in Saudi Arabia with 4.3 million inhabitants, and the gateway for pilgrims traveling to the holy cities of Madinah and Makkah.

SYSTRA Arabia’s scope of services comprises the feasibility and concept design of 57km of highway running from south of Obhur to Dahban, and includes the following studies:​

​

  • Land acquisition study​
  • Geotechnical and topographical surveys​
  • Scheme options and economic evaluation​
  • Highway design​
  • Hydrology​
  • Bridges (including iconic bridge over Obhur Bay)​
    • Iconic bridge will feature a bow-string structure reaching 51m at its peak​
    • Main span: 200m; total length of 2 km​
    • Bridge width: 74m, for a bay width of 360m​
  • Wet and dry utilities

The first phase of this project involves a feasibility study, including the development of five alignment options for the road corridor and Obhur Creek crossing, as well as traffic studies and the elaboration of a traffic model aligned with that of the city.

This phase includes a multi-criteria analysis, taking into account innovative solutions, technical difficulties, socioeconomic impact, the impact on traffic and project financing, ensuring a way forward for future phases.
