Dangerous structural defects on Mallam interchange
Mallam Interchange photographs taken last week have raised concerns about possible structural deterioration at one of the capital's busiest and most important road infrastructure assets, prompting calls for urgent safety assessments and maintenance. The images, captured at the beam-column junction beneath the flyover, appear to show signs of concrete spalling, sections of damaged concrete, and exposed reinforcement bars. A visible crack also runs from the damaged beam section towards the supporting column, raising concerns among observers about the structural condition of the facility and the need for a professional assessment.
The Mallam Interchange is a dual carriageway flyover that forms part of the George Walker Bush Highway, a six-lane, 14-kilometre corridor funded by the United States Millennium Challenge Corporation (MCC). Completed in 2012, maintenance of the interchange has since been managed by the Ghana Highway Authority (GHA). Concerns have been raised over the years about exposed expansion joints and other maintenance issues. Structural experts have previously warned that exposed reinforcement steel in concrete structures can increase the risk of corrosion, especially in coastal environments such as Accra.
