EIA for the proposed Hulhule-Male’ Bridge Project<br />

12 CONCLUSIONS<br />

The key conclusions of this EIA are summarized below.<br />

− The project involves the construction and operation of a bridge linking Hulhule and<br />

Male’ Island across Gaadhoo Koa atoll pass. This is the first bridge of its kind in the<br />

Maldives. The total length of the proposed bridge is 2 km; the section of the bridge that<br />

covers the overwater area across Gaadhoo Koa channel is 1.39 km. The elevation of the<br />

bridge is 20 m. The bridge landing area on Male’ side is next to the Tsunami Monument<br />

and onto the Boduthakurufaanu Magu. The landing area on Hulhumale’ is on the<br />

southern tip of Hulhule Island.<br />

− The structure is planned and designed to the environmental best practices suitable for<br />

the fragile environment of Maldives and the conditions in Male’. The design uses bored<br />

cast-on-site piles drilled to depths of up to 50 m from the reef pass bed. Pile-group<br />

foundation is proposed for the main piers and the transition piers. There will be 12 or 8<br />

main piers of bored piles with cross-sections ranging between 2.5 – 2.8 m. There will be<br />

6 transition piers of bored piles with a diameter of 1.6 m. The main bridge is a<br />

prestressed concrete six-span continuous rigid frame structure. The main bridge is 760<br />

m long. The approach bridge is pre-stressed concrete I-type beam bridge and is 630 m<br />

long. Land reclamation and shore protection is required at the southern tip of Hulhule<br />

island to facilitate the landing area. Sand for reclamation will be sought from<br />

Gulhifalhu reef.<br />

− The proposed developments are generally in conformance to the laws and regulations of<br />

the Maldives. Additional approvals are required for the following before<br />

commencement of project activities.<br />

o Detailed drawings approval from Ministry of Housing<br />

o Approvals from Ministry of Housing for construction in Male’<br />

o Approvals from City Council for road closure<br />

o Dewatering application and approval before commencement of any<br />

dewatering activities.<br />

o Approvals from Civil Aviation to operate the bridge on the southern end of<br />

Hulhule<br />

− The proposed site for the project is Gaadhoo Koa. On Male’ side, the structure utilises<br />

the gentle reef slope on the SE corner of Male’ to construct the bridge approach. The<br />

main pillars are located at 40 m depth on the channel bottom and the approach for<br />

Hulhule is partially on the Hulhule reef slope. The channel experiences strong tidal flow<br />

and receives strong swells from the SE direction. In particular, the wave conditions on<br />

the SE reef corner of Male’ and on the southern tip of Hulhule Island is particularly<br />
