Location Colombo, Sri Lanka

Client Road Development Authority / JICA

Project Period February 2013 – December 2013

New Bridge over the Kelani River

Problems addressed by the Project

Over 90% of freight transport is by road, so they are an essential transport infrastructure for the Democratic Socialist Republic of Sri Lanka.

The existing New Kelani Bridge, which is 1,160 m long and 6 lanes, is located in the northern part of Colombo. The bridge is a key link for transportation as three arterial roads connect to it.

Although three bridges including New Kelani Bridge are currently crossing the Kelani River, congestion has increased significantly in the past few years due to the rapid vehicle growth. It is severely affecting the economy of Sri Lanka. In addition, further traffic congestion is expected around the New Kelani Bridge, as a new expressway connecting the Bandaranaike International Airport is under construction and planned to open in 2014. The reduction of congestion in this area has become an urgent issue.

In order to address above issues, the Government of Sri Lanka has decided to construct a new bridge as a part of expressway over the Kelani River with support of Japanese ODA Loan.
