Today Transport Minister Dean Nalder officially declared the new Greenough River Bridge on the Brand Highway open.

The bridge is stage one of the State Government's Brand Highway development.

The new bridge was completed by contractor Georgiou Group Pty Ltd and it included 1.23kms of roadwork on both bridge approaches to realign the highway and another one kilometer of roadworks to realign the intersections with Reynolds Road and Hamersley Road.

"This new concrete bridge is much wider, longer and higher than the original structure built in 1953," Mr Nalder said.

"Opened to traffic in August, it improves safety for the almost 3000 vehicles that use this route everyday and will significantly reduce costs for the transport industry, which has previously cut off supplies to Geraldton and other nearby towns."

Mr Nalder said it was all about safety and mentioned that in 7 years there had been 20 crashes and 5 fatalities on this section of the Brand Highway.

Stage 2 of the project will include the realignment of the S-Bend.
