Construction of Box Culverts under Highway 55

The construction of 10-cell reinforced concrete box culverts beneath Highway 55 in the NEOM region represents a critical infrastructure advancement, seamlessly integrating functional design with operational precision to support the visionary development of the OXAGON and NEOM ecosystems. As a key transportation artery, Highway 55 demands uninterrupted mobility and utility continuity, necessitating a project that balances scale, complexity, and meticulous coordination. This endeavor involves excavating and processing an immense 1.5 million cubic meters of earth—a foundational step requiring advanced planning to ensure stability and alignment with geotechnical requirements. Over a 380-meter length, the construction of cast-in-place culverts, each cell measuring 3 meters by 3.5 meters, underscores the engineering rigor required to maintain structural integrity while accommodating future storm drainage demands. Waterproofing systems and systematic backfilling operations are incorporated to safeguard against long-term environmental and operational challenges, reflecting a commitment to durability and sustainability.

A defining challenge lies in executing these works under live traffic conditions, a feat achieved through rigorous traffic management strategies and collaboration with regulatory authorities to minimize disruptions. The project’s scope extends beyond civil works to include the protection, strategic diversion, and reinstatement of critical Ministry of Interior (MOI) and Information and Communications Technology (ICT) cable networks, ensuring uninterrupted services during and after construction. Upon completion, full highway reinstatement will restore the corridor to its original operational state, adhering to stringent quality and safety standards. By executing this high-stakes project—marked by its scale, technical intricacies, and constraints of working in proximity to active infrastructure—Abyatona demonstrates its proficiency in delivering complex, large-scale solutions under demanding conditions.
