TYPE OF PROJECT: Design and Build of a multi-span steel flyover​​

CLIENT: Road Development Authority, Ministry of Highways and Investment Promotion

SUMMARY: The Flyover is located at in the town of Veyangoda on the Nittambuwa-Katunayake Road (B208) that at this point crosses the railway line to Colombo. Veyangoda is a popular railway hub located in the center of the Gampaha District in the Western Province. As an important “dormitory town” it generates a large volume of commuter trips to and from Colombo by road and train. There are a very high number of trains passing through the Veyangoda railway station daily, as well as cars and buses that must cross the train satiation in their way to the capital city, a major economic center, and industrial suburbs. These trains are from both the Main Line going up to Peradeniya and beyond as well as from the Northern Line going up to Maho and beyond.

CENTUNION carried out the design, fabrication, and construction of the multi-span straight steel ladder bridge, with two ramps and two approach roads having a total length of 315 m. Considering the urgency and necessity of the project, a steel deck panel solution was installed to reduce construction time, while prefabricated steel columns with bored piles foundations were used as piers. A total number of 7 spans were needed with a vertical clearance of 6.95m to overs pass crossing for roads and railways. Centunion is proud to say that the Veyangoya infrastructure was completed and operational in an extremely short time of 12 months, without interrupting the train service during the whole construction period.
