Dawson Highway (Banana - Rolleston), Roundstone Creek, replace bridge Dawson Highway (Banana - Rolleston), Roundstone Creek bridge, replace overflow

A new wider and higher concrete bridge has replaced the timber bridge at Roundstone Creek on the Dawson Highway.

Roundstone Creek Bridge was built in 1945 and was one of the few remaining timber bridges on the Dawson Highway.

As part of an ongoing program of works to replace timber bridges in the Fitzroy District, the ageing structure has been replaced with a new concrete bridge capable of supporting future growth in the agricultural and freight industries.

Works also included upgrading the nearby intersection with Glenmoral Roundstone Road to accommodate B-doubles (a prime mover with 2 semitrailers).

In addition, the Roads of Strategic Importance (ROSI) initiative provided $6 million to improve existing culverts and install new structures to improve flood immunity. These works were part of the supporting Roundstone Overflow project.

Overall, these works have provided improvements in safety and flood immunity that will benefit everyone who uses this section of the Dawson Highway.
