The Fourth Corridor announcement on 16 September 2026 comes with an unusual amount of quantified detail for a road that has no contractor or completion date yet, which makes it a decent small dataset for anyone tracking Dubai infrastructure as a leading indicator for property prices.
The headline numbers: 80 kilometres, 12 lanes across both directions, 72 bridges, 17 tunnels, 45 stormwater culverts, and a stated capacity of 24,000 vehicles an hour. Those are design specifications from the approval itself, not projections, so they are as firm as this stage of a project gets.
Where the softer numbers come from
Phase 1 (Sharjah to the Dubai-Al Ain Road, about 30 kilometres, AED 3.5 billion) carries a travel time claim of 35 minutes down to 14, a 60 per cent cut, covering roughly 600,000 people. Phase 2 (50 kilometres, to Al Faya Road) claims 50 minutes down to 24. Combined, the government puts served population at 3.1 million once both phases are open. These are modeled travel time and population figures, so treat them as planning assumptions rather than measured outcomes.
For anyone modeling area-level effects, the useful variables here are per-phase cost per kilometre, the lane-widening on the Dubai-Al Ain Road (3 to 4 lanes between Emirates Road and Lehbab Road), and the 4 intersections named for upgrade, since those are the points most likely to show up first in permit or transaction data. Doment's area guides cover the communities along the route if you want to cross-reference.
