The Shahid Kalantari Freeway and Lake Urmia Causeway Project is a major national and regional infrastructure development in Iran, characterized by complex engineering requirements, environmental sensitivities, and unique geographical conditions. The project connects Tabriz and Urmia via a causeway across Lake Urmia, reducing the distance between the two cities from 258 km to 126 km.
The causeway section extends approximately 15.4 km across the lake, comprising a total of 14 km of embankments and a 1,250 m bridge connecting the two embankments. The bridge consists of 21 spans and is 26.7 m wide.
Tarh Novandishan Engineering Company, in collaboration with the Danish consulting firm COWI, provided consultancy services to the project owner. The scope included feasibility studies for routing oil facilities through the causeway, preliminary studies, review and verification of existing study data, evaluation of contractors’ proposals, and assessment of alternative causeway connections.
The consultancy team also evaluated design-build contractors’ proposals for the causeway bridge and carried out preliminary and detailed studies for the Tabriz–Urmia Freeway. During construction, the team reviewed the bridge contractor’s engineering documents and supervised construction of the causeway and freeway.
