The New Orbital Highway Contract 2 stemmed from the intention to bypass Doha City by connecting Salwa Road and North Relief Road, thus relieving the existing traffic congestion expected to increase in the coming years.
Located in the north west of Doha, NOH2 consists of ten lanes (five in each direction) for light vehicles with additional collector / distributor roads.
Four separate dedicated truck lanes (two in each direction) run parallel to the Orbital from Salwa Road to Junction 5 where a 320 m long cut and cover tunnel splits away from the light vehicle carriageway towards Junction 12, Dukhan interchange.
