Dubai Approves Dh3.5 Billion Phase 1 of 80km Fourth Corridor to Cut Inter-Emirate Travel Times by 60 Percent

Dubai has approved the development of an 80-kilometer Fourth Corridor, a major transport infrastructure project designed to reduce inter-emirate journey times by up to 60 percent while connecting Abu Dhabi, Dubai, and Sharjah. Phase 1 represents a Dh3.5 billion investment approved by Sheikh Hamdan bin Mohammed bin Rashid Al Maktoum, Crown Prince of Dubai and Chairman of the Executive Council.

The high-capacity highway will feature 12 lanes in both directions, capable of handling 24,000 vehicles per hour to support more than 3.1 million residents and freight operators across the United Arab Emirates. Official project announcements are tracked via Government of Dubai Media Office.

Engineering Scope and Inter-Emirate Route Alignment

The Fourth Corridor forms a continuous transit artery extending from Dubai's Abu Dhabi border to its Sharjah border. The route links Al Shanoof Street in Sharjah directly with the Dubai-Al Ain Road, heading towards Abu Dhabi.

Constructed under the oversight of transport authorities including Roads and Transport Authority Dubai (RTA), the corridor incorporates major structural features:

• Capacity Infrastructure: 12 total lanes across both directions with a throughput capacity of 24,000 vehicles per hour.
• Bridges & Tunnels: Construction of 72 elevated bridges and 17 underpass tunnels to ensure uninterrupted traffic flow.
• Environmental Drainage: Installation of 45 stormwater drainage culverts to maintain highway safety during severe rainfall events.
• Multimodal Integration: Direct road connections to Al Maktoum International Airport (DWC) and freight terminals operated by Etihad Rail Official Site.

Structural Engineering	72 bridges and 17 tunnels
Drainage System	45 specialized stormwater culverts
Primary Terminal Connections	Al Maktoum International Airport (DWC), Etihad Rail Network
Impact Projection	Up to 60% reduction in inter-emirate transit times

Economic and Strategic Logistics Impact

By establishing a fourth major arterial bypass alongside Sheikh Zayed Road (E11), Sheikh Mohammed bin Zayed Road (E311), and Emirates Road (E611), the project alleviates heavy commercial traffic between industrial zones in Sharjah and Abu Dhabi.

The direct highway link to Al Maktoum International Airport (DWC) supports Dubai's master plan to transition international passenger and cargo operations to the expanded facility. Freight transport efficiency is further enhanced by synchronization with Etihad Rail freight depots, allowing seamless container transfers between road and rail networks.

Traveler Logistics Guide for UAE Inter-Emirate Transit

Drivers and commuters navigating the UAE highway system during and after corridor construction should plan itineraries around updated traffic patterns:

Route Selection for Inter-Emirate Travel

• Sharjah to Abu Dhabi Commuters: Drivers traveling between Northern Emirates (Sharjah, Ajman) and Abu Dhabi can bypass inner Dubai city congestion by taking the Fourth Corridor via Al Shanoof Street to the Dubai-Al Ain Road interchange.
• Airport Transfers (DXB vs DWC): Passengers transferring between Dubai International Airport (DXB) and Al Maktoum International Airport (DWC) will experience transit times reduced from 55 minutes to under 30 minutes once fully operational.

Toll and Digital Driving Regulations

• Salik Toll System: Like existing Dubai highways, automated Salik toll gates will monitor vehicle entries along designated interchange zones. Rental vehicles should confirm active Salik tag registration.
• Speed Limits and Heavy Vehicle Windows: Standard UAE highway speed limits (typically 110 km/h to 120 km/h with radar enforcement buffer rules per emirate) apply. Heavy trucks must adhere to restricted lane usage and peak-hour movement bans.
