Manampitiya Bridge, Road-rail bridge in Polonnaruwa District, Sri Lanka.

Manampitiya Bridge consists of two parallel crossings of the Mahaweli River: a 291 m steel railway bridge built in 1922, less than 5 m wide, and a newer highway bridge carrying two lanes of the A11 road. Together they measure 302 m, making the crossing Sri Lanka's second longest bridge.

The original steel bridge was completed in 1922 during British colonial rule and served as the main link between the eastern and central regions for more than eight decades. A newer structure later replaced the historic crossing to meet increasing transportation demands.

The bridge has become a symbol of national progress and appears on the Sri Lankan 50 rupee banknote as a mark of its importance to the country. This recognition reflects how the structure represents development and connectivity for local people.

The bridge carries the A11 Habarana–Thirikondiyadimadu road across the Mahaweli, 81 km east of Maradankadawala, linking North Central and Eastern provinces. The 1922 steel span, under 5 m wide, is reserved for rail traffic, while vehicles use the two-lane 2007 bridge beside it. Cross on foot or by vehicle on the road deck; the railway deck is not open to pedestrians.

The newer span is officially named the Sri Lanka-Japan Friendship Peace Bridge, funded by a LKR 1.3 billion grant from the Japan International Cooperation Agency. The 50 rupee note in circulation carries an image of the Manampitiya Bridge.
