The Kinniya Bridge which was considered as the longest bridge in Sri Lanka is now considered as the second longest bridge with a length of 396 meters (1,299 ft). The two-lane bridge was built with the financial support from the Saudi Arabian government and declared opened to public on 20th October 2009. The Benthara bridge on the Southern Expressway across the Benthara river has become Sri Lanka's longest bridge with 695 metres in length.
The Bridge crosses Koddiyar Bay on one side and Tambalagam Bay on other side and links Trincomalee with Kinniya and Mutur, enabling civilians to cross Kinniya lagoon easily by the A15 highway.
With the opening of this bridge, the old ferry service that operated through the Kinniya lagoon for years from morning to late evening, carrying both passengers and vehicles, was abandoned. Some boat owners operate boat tours from the former ferry point on your request which takes you on a ride under the bridge and surrounding sea. It costs you around Rs. 600 per ride. Life jackets are not provided. It is a wonderful place for nature lovers as the view from the bridge on either side gives incredible spirits.
