Located in the Emirate of Umm Al Quwain in the United Arab Emirates, the Siniya Island Causeway is a major infrastructure project establishing a direct road link between the E11 highway and Siniya Island. This strategic connection supports the island’s future development by enabling access to key utilities including potable water, power transmission, telecommunications, stormwater drainage, and public lighting.
The project includes the construction of a new 38-metre right-of-way triple carriageway and a roundabout integrated into the existing E11 road. The alignment passes through the former UAQ Aviation site, which required the clearance of existing structures to enable the new infrastructure. The road continues across a newly built causeway and bridge, ending on the island to connect with future developments.
Geoquest unit of Freyssinet Middle East designed, supplied, and supervised the installation of crossing structural elements.
The proposed 1 km causeway—comprising 680 metres of bridge and 400 metres of embankment—is supported by TechSpan arch structures and Reinforced Earth walls. The dimensions of the arches were defined to ensure clear and safe passage for marine vessels beneath the bridge. The crossing accommodates three active navigation channels, all of which were maintained throughout construction and at final handover.
Launched in January 2022 and completed in November 2024, this landmark project showcases Geoquest’s expertise in delivering critical infrastructure in complex environments.
We are proud to have collaborated with BATCO Group, the main contractor, and to have contributed under the leadership of the Umm Al Quwain Properties development authority. We thank our partners for their trust and look forward to the long-term impact this new connection will have on the region’s accessibility and growth.
