Projects will include a 22km 'East West Corridor' dual carriageway linking Hamad International Airport to the New Orbital highway and truck route, with five lanes in each direction and eight interchanges giving new links to main roads and residential areas, the report said.
An 11km dual carriageway bypass will be created for Al Wakra city, including a tunnel and five interchanges that link the south of Al Wakra city to Hamad International Airport and the New Doha port. This will link Mesaieed and Al Wakra directly to Doha city.
Both projects are expected to be complete by the first quarter of 2018, the Peninsula said.
A third project will involve further work on the New Orbital route, as part of a four-stage plan to build a 190km highway with separate lanes for heavy trucks, the Peninsula said. The first stage of this will be a 45km dual carriageway to the south-west of Doha, and a road linking Mesaieed road to the East West Corridor.
Infrastructure improvements will also include storm water drainage, sewage treatment, electrical, telecommunications and surveillance networks, street lighting and dedicated lanes for pedestrians and cyclists, the Peninsula said.
Doha-based Jonathan Collier of Pinsent Masons, the law firm behind Out-Law.com. said: "The news will be well received, following the announcement earlier this year that non-essential infrastructure schemes including the Sharq Crossing, would be postponed. The project will also appease some critics who have concerns that too much infrastructure attention is placed on Doha, ignoring the needs of other areas."
