Qatar’s capital city Doha is home to nearly 2 million people. Doha’s population is rising along with the growing number of tourists to the city, who come to attend some of the world’s most popular sporting events.
Transport is a top priority and Qatar’s Greater Doha traffic master plan provides a solution for future transport needs. Sharq Crossing, an ambitious bridge and tunnel system, is a strategic element of this plan. The crossing will span Doha Bay, linking the new Hamad International Airport and the capital’s business and leisure districts. It is expected to solve the city’s congestion issues when it is completed in 2020.

TEC, the permanent joint venture between Royal HaskoningDHV and Witteveen+Bos, is validating the conceptual tunnel design on behalf of Santiago Calatrava, architect of the Sharq Crossing. The Sharq Crossing is one of the most iconic and prestigious bridge-tunnel connections we have been commissioned to work on to date, and the first ever immersed tunnel project in the Middle East region. 

We are designing two immersed tunnels and three cut-and-cover tunnels that will connect the bridges to the mainland. The assignment further includes design of bridge foundations, roads, utilities, safety, mechanical, electrical and plumbing systems, and planning. 

Santiago Calatrava said: “Sharq Crossing will be a new icon for Qatar’s capital, improving transport for Doha citizens and tourists. It will help receive all visitors to the 2022 FIFA World Cup events.” 

Tunnel innovation at its best

The Immersed tunnels are composed of 25 m segments constructed in a dry dock. They are joined to form longer tunnel sections of 150 m or more and floated to the tunnel site where they are submerged and linked together. The benefit of this type of tunnel is that it reduces construction time and impact on shipping and in many cases it provides a cost effective solution for river crossings when compared to bridges or bored tunnels, especially when such rivers have to cater for ocean going vessels.
