The current phase of the 9.5km project will complete in Q3 2015 and the USD 120M project by the first quarter of 2017.
The main tunnel will run along F-Ring Road from the Mesaimeer roundabout (Woqod petrol station) and reach the sea to the south of Hamad International Airport, according to the report.
Flooding in parts of the Salwa Road following heavy rainfall in March was attributed to the lack of an outlet to dispose of the excess water that had accumulated in the drainage system.
