Situation de départ

M1 Freeway is the part of the National Road Network and connects Sydney to Newcastle. It is a three-lane freeway cutting through high sandstone cuttings. Historically the solution has been spot bolting as a means of addressing small rockfall. After a long study, it was determined that the ideal solution would be mesh drapes.

Description

We supplied 14‘000  of G80/3 (powdercoated matt black) for the drapes and 570 l/m of T10 Barriers in three sections also powdercoated black.
