Dubai Unveils 80km Fourth Corridor Road Project to Boost Inter-Emirate Connectivity

Dubai has approved the 80-kilometre Fourth Corridor project, a major infrastructure initiative connecting Sharjah, Dubai, and Abu Dhabi, designed to significantly improve regional road network efficiency.

Dubai has announced a substantial infrastructure development with the approval of the new 80-kilometre Fourth Corridor road project. This initiative aims to strengthen the emirate's road network and enhance connectivity across the UAE, specifically linking Sharjah, Dubai, and Abu Dhabi.

Approved by Crown Prince of Dubai and Chairman of the Executive Council Sheikh Hamdan bin Mohammed bin Rashid Al Maktoum, the corridor will span from Al Shanouf Road in Sharjah to Al Faya Road in Abu Dhabi.

Project Scope and Phased Implementation

The Fourth Corridor will be implemented in two distinct phases:

Phase 1: Estimated to cost approximately 3.5 billion UAE dirhams (US$953 million), this phase will extend from Al Shanouf Road in Sharjah to Dubai-Al Ain Road.
Phase 2: This phase will continue the corridor from Dubai-Al Ain Road to Al Faya Road in Abu Dhabi.

The entire corridor is designed to include 72 bridges and 17 tunnels, offering a substantial capacity for 24,000 vehicles per hour in both directions. This extensive infrastructure is projected to reduce journey times by up to 60 percent and benefit an estimated 3.1 million people.

Strategic Connectivity and Impact

Beyond improving inter-emirate travel, the project is also set to enhance connectivity with key regional hubs, including Al Maktoum International Airport and the Etihad Rail network. This new corridor will supplement Dubai's three existing inter-emirate routes: Sheikh Zayed Road, Sheikh Mohammed bin Zayed Road, and Emirates Road, further integrating the UAE's crucial economic and residential centres.
