Government plans next phase of expressway expansion as attention turns to economic returns rather than road length
COLOMBO, Friday – The Government’s announcement that Sri Lanka’s expressway network is set to expand by a further 132 kilometres over the coming years has renewed discussion over the role of modern transport infrastructure in driving economic growth. While the construction of new highways has often been measured by the number of kilometres completed, economists argue that the more important question is whether those roads generate measurable returns for the national economy.
Successive administrations have invested heavily in expressway construction, linking Colombo with the Southern Province, the airport, the Central Province and parts of the North-Western region. Those projects have dramatically reduced travel times and improved road safety, but they have also required substantial public investment financed through a combination of domestic and foreign borrowing.
The proposed expansion seeks to strengthen links between key commercial centres while improving access to emerging industrial zones, tourism destinations and regional markets. Government planners believe that improved connectivity will reduce logistics costs, encourage private investment and improve the competitiveness of Sri Lankan exports.
Business leaders have long argued that transport costs remain one of the hidden burdens affecting the competitiveness of local industry. Delays in moving goods between factories, ports and airports increase production costs and reduce efficiency. Modern highway infrastructure, they contend, can improve productivity in much the same way as reliable electricity or efficient telecommunications.
Tourism is also expected to benefit from improved road connectivity. Shorter travel times between Colombo, the hill country, the cultural triangle and the southern coastline allow visitors to experience more destinations during a single visit, increasing tourism spending across a wider geographical area.
Infrastructure specialists caution, however, that expressways alone cannot transform an economy. The greatest returns are achieved when road development is accompanied by industrial investment, logistics hubs, commercial centres and urban planning designed to maximise economic activity along the new transport corridors.
The challenge facing policymakers is therefore broader than building roads. It is about ensuring that every kilometre of expressway generates employment, investment and productivity gains that justify the substantial public resources committed to their construction. If that objective is achieved, the next 132 kilometres may be remembered not merely as another engineering project but as an investment in Sri Lanka’s long-term economic competitiveness.
