🚧 Lagos Announces 18-Week Maintenance on Mazamaza Bridge Ahead of Blue Line Rail Expansion

The Lagos State Government has announced an 18-week maintenance programme for Mazamaza Bridge along the Lagos–Badagry Expressway, a key transport corridor linking Mile 2 to Badagry.

The maintenance works will begin on Monday, 19 January 2026, and run through Thursday, 28 May 2026, as part of preparations for the Blue Line Rail Phase 2 extension from Mile 2 to Okokomaiko.

🛠️ What’s Happening on the Bridge?

According to the Commissioner for Transportation, Oluwaseun Osiyemi, the repairs will focus on:

• Expansion joints

• Critical structural bridge elements

• Both Toll and Service Lanes

• Inbound and outbound traffic directions

Despite the scale of the work, the bridge will not be completely closed at any time.

🚦 Traffic Diversions to Expect

To manage movement and reduce disruption, traffic will be diverted across:

• Toll Lanes

• BRT Corridor

• Service Lanes

Motorists should expect lane restrictions throughout the 18-week period.

A preliminary phase from 24–30 January will set up work zones and assess traffic flow.

• Phases 1–4 (31 Jan – 30 Mar): Repairs on Badagry-bound lanes

• Phases 5–8 (31 Mar – 2 Jun): Repairs on Lagos-bound lanes

During works:

• The BRT corridor will temporarily serve as a diversion when Toll Lanes are under repair.

• The Toll Lane will later act as a diversion when work shifts to the BRT corridor.

• Service Lane repairs will temporarily reduce traffic to one lane before reopening fully.

👮🏾 Safety Advisory for Motorists

Drivers have been advised to:

• Obey road signs

• Follow instructions from Lagos State Traffic Management Authority (LASTMA) officials

• Plan journeys ahead to avoid delays

🚆 Why the Bridge Will Be Rebuilt

In December 2024, LAMATA’s Director of Rail Transport, Olasunkanmi Okusaga, revealed that structural assessments showed the current bridge cannot support rail operations.

The planned replacement bridge will:

• Be built to international standards

• Be supported by 66 piers

• Have a projected lifespan of at least 75 years

For now, commuters along the Lagos–Badagry corridor should brace for slower traffic — but with the promise of long-term infrastructure upgrades ahead.
