As heavy rains once again submerged parts of Lekki in 2026, fingers pointed squarely at one of Nigeria’s most ambitious infrastructure projects: the Lagos-Calabar Coastal Highway. Residents in communities like Baruwa/Igbo Efon reported persistent flooding, damaged homes, and contaminated water, linking it directly to open drainage channels and disruptions from the highway construction.
Key Highlights:
- Officials defend project: The government says the Lagos-Calabar Coastal Highway is designed to reduce flooding, not cause it.
- Residents raise concerns: Lekki communities blame ongoing construction for worsening floods and property damage.
- Flooding has many causes: Poor drainage, low-lying terrain, rapid development, and heavy rainfall all contribute.
- Construction poses short-term risks: Temporary drainage disruptions have increased flooding in some areas.
- Better implementation is key: Stronger drainage management and government coordination are needed to deliver long-term flood protection.
Yet federal and state officials, led by Works Minister David Umahi and Lagos Governor Babajide Sanwo-Olu, firmly maintain the opposite: the highway is engineered to fight flooding, not worsen it.
The Official Defense: A Flood-Fighting Design
Minister Umahi has repeatedly emphasized during site inspections and stakeholder engagements that the highway incorporates advanced drainage systems, including multiple culverts and channels designed to evacuate stormwater and shield communities from ocean surges. The project’s elevated structure and comprehensive Environmental and Social Impact Assessment (ESIA) were highlighted as safeguards, with claims that pre-construction flooding along the corridor was already severe due to the area’s low-lying terrain.
“The coastal highway is actually addressing flooding within this corridor, not causing it,” Umahi stated. He pointed to human factors—indiscriminate refuse dumping, blocked manholes, vandalism of drainage infrastructure, and Lagos State’s failure to fully implement its master drainage plan—as the primary culprits behind recent inundations.
The Contractor Hitech Construction echoed this, attributing issues in Lekki estates to inadequate land elevation and poor internal drainage planning in developments built without proper foresight.
Lagos has battled annual flooding for decades, with records dating back to the 1960s, driven by its coastal geography, high water table, rapid urbanization, and climate-driven heavier rains. Officials argue the highway’s long-term benefits—better water management across a 750km corridor spanning multiple states—will outweigh temporary construction disruptions.
On-the-Ground Reality: Resident Suffering and Construction Complaints
Despite the assurances, community leaders paint a different picture. In June 2026, residents in Baruwa/Igbo Efon petitioned authorities, claiming over 250 houses face direct risks from an open water discharge drain tied to the coastal road project. Floodwaters have damaged properties, weakened structures, disrupted access, and raised health concerns from stagnant, contaminated pools. Similar alarms have been raised in Ibeju-Lekki areas, where blocked or redirected channels allegedly exacerbate overflow during rains.
Construction activities—earthworks, reclamation, and temporary drainage diversions—inevitably alter local hydrology. Critics note that while the finished highway may include robust systems, the ongoing phase has created vulnerabilities, especially where natural flow paths were interrupted without immediate, adequate mitigation. Lekki’s boom in estates, often on reclaimed or low-lying land without sufficient elevation or connected drains, compounds the problem.
Social media and local reports frequently show submerged roads, stranded vehicles, and frustrated homeowners, fueling narratives that the massive project prioritizes connectivity and economic gains over immediate livability in affected zones.
Root Causes Run Deeper Than One Highway
Lagos flooding is systemic. Key contributors include:
Poor urban planning and blocked drains — Refuse, silt, and informal structures routinely choke waterways.
Low elevation and reclamation — Much of Lekki sits vulnerable to rain and surges.
Climate and rainfall intensity — Heavier, more frequent downpours strain aging or insufficient infrastructure.
Rapid development — Estates and roads often outpace drainage upgrades.
The coastal highway did not invent these issues, but segments under construction can act as flashpoints if drainage is not seamlessly managed in real time.
A Balanced Path Forward
The Lagos-Calabar Coastal Highway represents a generational opportunity for Nigeria’s southwest coast: enhanced connectivity, economic stimulus, job creation, and potentially superior flood infrastructure compared to the status quo. Its design philosophy—elevated alignment with dedicated evacuation channels—aligns with best practices for coastal resilience.
However, “strong on paper” must translate to “effective on ground.” Temporary impacts during multi-year construction require aggressive mitigation: faster completion of drainage segments, community engagement, real-time hydrological monitoring, and stricter oversight of nearby developments. Lagos State must pair the federal project with its own master plan enforcement—desilting, enforcing building codes, and upgrading secondary drains.

Residents deserve relief now, not promises of future benefits. Joint federal-state inspections are a positive step, but sustained transparency, independent audits, and adaptive engineering adjustments will determine whether the highway ultimately earns its title as a flood mitigator—or remains a lightning rod for Lekki’s water woes.
The final verdict? The project is not the root villain in Lekki’s floods, but it cannot be absolved of all responsibility during its build phase. With rigorous execution and complementary local action, it can shift from controversy to cornerstone of a more resilient Lagos coastline. Nigerians will be watching.
