Central Expressway (Sri Lanka) The Central Expressway is a major high-capacity road project in Sri Lanka designed to connect the Colombo District periphery with the central and north-central regions, improving links between Kadawatha, Mirigama, Gampola, and Dambulla. Conceived amid national drives for infrastructure expansion under administrations including Mahinda Rajapaksa and Maithripala Sirisena, the expressway intersects strategic corridors serving Colombo port logistics, tourism nodes like Sigiriya, and agricultural belts near Anuradhapura.
The route aims to deliver a limited-access, multilane motorway comparable to projects such as the Southern Expressway (Sri Lanka), the Kandy Road, and international examples like the Delhi–Mumbai Expressway; its design standards reference practices from the Japan International Cooperation Agency and contractors from China Road and Bridge Corporation and China Harbor Engineering Company. The corridor is expected to relieve pressure on arterial routes including the A1 (Sri Lanka) and A6 (Sri Lanka), integrate with the Colombo Port City hinterland, and support national plans promoted by the Ministry of Highways (Sri Lanka) and development financiers such as the Asian Development Bank and bilateral lenders.
Phasewise alignment runs from Kadawatha near the Outer Circular Expressway junction through Gampaha District and Kurunegala District into the foothills of the Central Province, passing close to Mirigama, Polgahawela, Pothuhera, and Rambukkana before traversing toward Gampola and the Kandy District approaches, with the ultimate aim to reach Dambulla in the Madhyama Province-adjacent region. The expressway interfaces with existing highways such as the A10 (Sri Lanka) and the A9 (Kandy–Jaffna) corridor, and provides improved access to nodes like Katugastota, Peradeniya, and cultural sites associated with Buddhist pilgrimage routes and UNESCO-linked locations including Sacred City of Kandy.
Initial feasibility and alignment studies drew on precedents from infrastructure programs overseen by figures like Nimal Siripala de Silva and were influenced by national plans promoted during the Mahinda Chintana policy era and subsequent five-year development frameworks under Ranil Wickremesinghe. Early proponents cited connectivity benefits to commodity chains serving Ceylon Tea estates around Nuwara Eliya, rice cultivation in the North Central Province, and tourism circuits centering on Sigiriya and Dambulla Cave Temple; feasibility work referenced technical standards from Japan and financing models used in the China–Sri Lanka relations context.
Construction has been divided into prioritized sections: Section I (Kadawatha–Mirigama), Section II (Mirigama–Kurunegala), Section III (Kurunegala–Dambulla via Gampola), and later linkages toward Matale and Dambulla. Contractors have included consortia affiliated with China Communications Construction Company and local firms registered with the Road Development Authority (Sri Lanka), employing engineering methods seen in projects like the Colombo–Katunayake Expressway and the Airport Expressway (Colombo) upgrade. Works have encountered scheduling shifts paralleling other national projects such as the M6 (Sri Lanka) and coordination with utility agencies including CEB and the National Water Supply and Drainage Board.
Operational management is slated to follow toll-based revenue models similar to the Southern Expressway tolling framework and incorporates electronic toll collection trials inspired by systems in Singapore and Malaysia. The Road Development Authority (Sri Lanka) and the Ministry of Transport coordinate tariff structures, with expected integration into national vehicle registration databases managed by the Department of Motor Traffic (Sri Lanka)]. Toll plazas are planned at strategic interchanges near Kadawatha, Mirigama, and Polgahawela with provisions for exemption and concession arrangements for stakeholders analogous to concessions seen in the Colombo Port City and Hambantota Port agreements.
Proponents argue the expressway will catalyze investment in manufacturing zones similar to those in Katunayake and Koggala, boost tourism to heritage sites like Sigiriya and Dambulla Cave Temple, reduce logistics costs for plantation exports to Colombo Port, and spur urbanization around nodes such as Kurunegala and Gampola. Critics have highlighted displacement concerns affecting communities in the Gampaha District and land title disputes reflecting precedents from projects like the Hambantota Port Special Economic Zone and legal challenges heard in the Court of Appeal (Sri Lanka). Employment creation during construction echoed outcomes observed in the Southern Expressway rollout.
The alignment crosses varied terrain including lowland plains near Kelani River catchments and upland foothills adjoining the Knuckles Mountain Range, raising issues mirrored in environmental assessments for the Upper Kotmale Hydropower Project and biodiversity considerations in Ruhunu National Park. Engineering challenges include constructing viaducts over flood-prone zones, stabilizing slopes in lateritic soils near Kegalle District, and mitigating impacts on groundwater used by tea plantations around Nuwara Eliya. Environmental Impact Assessments incorporated mitigation measures similar to those recommended by International Finance Corporation performance standards and resettlement frameworks aligned with models from the Asian Infrastructure Investment Bank.
