William Walter Mason Bridge

The  William Walter Mason Memorial Bridge (also known as  Barron River Bridge ) is a road bridge that carries the Captain Cook Highway across the Barron River at the boundary of four suburbs in Cairns (Stratford, Aeroglen, Barron, and Machans Beach) in the Cairns Region, Queensland, Australia.

The first Barron River Bridge was built by John Holland Constructions in 1977. On 12 August 1978 it was named after William Walter Mason, the first settler who bought land on the north side of the Barron River in 1882.

The first bridge was converted to southbound traffic after the second northbound bridge was built in 1988 as part of the highway duplication project. Both bridges are known as the William Walter Mason Bridges.
