Dubai has approved the construction of the new fourth corridor, a major highway programme aimed at boosting inter-emirate connectivity, increasing road capacity and easing congestion.

The corridor will extend 80 kilometres, from Al-Faya Road in Abu Dhabi to Al-Shanouf Road in Sharjah.

It will include 12 lanes, 72 bridges and 17 tunnels.

The project is expected to reduce travel times by up to 60% and serve more than 3.1 million people, while providing links to Al-Maktoum International airport and Etihad Rail.

It will have the capacity to accommodate 24,000 vehicles per hour in each direction.

The project will be delivered in two phases. The first phase, running from Al-Shanouf Road to Dubai-Al Ain Road, will be delivered at a cost of AED3.5bn ($953m).

The second phase will stretch from Dubai-Al Ain Road to Al-Faya Road in Abu Dhabi.

The scheme adds a fourth spine to a network that has long relied on three main corridors: the E11 (Sheikh Zayed Road/Al-Ittihad Road); the E311 (Sheikh Mohamed Bin Zayed Road) and the E611 (Emirates Road), which together carry more than 850,000 vehicles commuting between Dubai and the northern emirates daily.

That concentration has made the route one of the country’s most congested, with peak-hour bottlenecks a persistent problem for residents. The new corridor is designed to divert a significant share of that traffic onto a higher-capacity route, rather than add pressure to the existing network.

The project also aligns with the Dubai 2040 Urban Master Plan, which anticipates population growth to 5.8 million by 2040 and calls for the expansion of roads, railways, airports and ports to support that growth and reinforce Dubai’s position as a global trading hub. This is reflected in the corridor’s direct links to Al-Maktoum International airport and Etihad Rail.
