Prai River Bridge, Cable-stayed bridge over the Perai River in Seberang Perai, Penang, Malaysia.

Prai River Bridge is a 1.85-kilometre dual-three-lane cable-stayed bridge over the Perai River in Seberang Perai, Penang, part of the Butterworth Outer Ring Road. Its two 40-metre reinforced concrete pylons each carry 14 pairs of stay cables, supporting a 185-metre glued-segmental main span and 22 precast approach spans.

The bridge opened in 2005 as project 1B of the Butterworth Outer Ring Road (BORR), built under a turnkey contract by Lingkaran Luar Butterworth (Penang) Sdn. Bhd. to a design by Dar Al-Handasah Consultants. Ballast Needam International left the project halfway; IJM Construction Sdn. Bhd. and Zublin International (Malaysia) Sdn. Bhd. completed the works in joint venture. In 2006 the bridge won the IStructE Award for Transportation Structures and the institute's Supreme Award.

The bridge carries the Butterworth Outer Ring Road across the Perai River in Seberang Perai, linking the mainland districts of Butterworth and Perai. Its name in Malay is Jambatan Sungai Perai, and it forms project 1B of the BORR scheme. The crossing was opened to traffic in 2005.

The bridge carries the Butterworth Outer Ring Road (BORR) across the Perai River as project 1B of that road, linking the new ring road with Butterworth. Its dual-three-lane approaches are 27.8 m wide and the main deck 28.8 m wide, with three precast segmental entry and exit ramps feeding the crossing. Drivers reach it via the BORR on the Seberang Perai side.

The bridge won the Institution of Structural Engineers' Supreme Award in 2006, alongside its Award for Transportation Structures. Its 185 m main span was erected by cantilever method from glued precast segments, and each of the two 40 m pylons carries 14 pairs of stay cables.
