The Gold Coast Council has potentially found a new way to reduce landfill, by using recycled glass, tyres and plastic for roads.

A 410-metre long stretch of KP McGrath Drive in Elanora is the first to trial the use of recycled materials, using crushed glass making up the lower layer of the road and plastic car bumpers for the upper layer.

Acting Mayor Donna Gates says using recycled materials reduces the need to buy sand as well as asphalt, and hopes the trial in Elanora will result in a long-lasting road at an improved price.

Mrs Ross says people driving through suburbs such as Albion and Newmarket should keep in mind there may be water over the road, adding it is never safe to drive through flood water.
