Accelerated demographic growth and rapid economic development have led to increases in population and traffic in Abu Dhabi, the capital of United Arab Emirates. The Abu Dhabi Government is implementing various initiatives to develop surface infrastructure to enhance quality of life in the city.
The Al Salam Street Project is an initiative by Abu Dhabi Municipality to transform the existing Al Salam Street (renamed as Sheikh Zayed Street in December 2012) alignment into an uninterrupted traffic corridor. The project has a series of tunnels, surface roadways and junctions to ease traffic congestion. The Abu Dhabi Municipality is financing the AED5bn ($1.36bn) contract.
The project involves four sections running from Al Salam Bridge to Al Mina Street and consists of five tunnels, a bridge, bypasses, surface and service roads.
The Sheikh Zayed Street Improvement Project consists of four construction contracts for grade-separated interchanges, tunnels, road widening and other improvements.

The 3.6km tunnel, the longest tunnel in the Middle East was opened in December 2012. The tunnel has four lanes in each direction and reduces the travel time from Sheikh Zayed Bridge to Mina Street to 20 minutes.

The tunnel is equipped with several latest facilities for effective operation of the tunnel. The Sheikh Zayed Street was opened to public in December 2012.
