A.D. Engineering International is proud to be part of WA’s biggest road project to date.

The Gateway WA project incorporates road and bridge improvements, local road modifications, facilities and connections for pedestrians and cyclists, noise walls, landscaping and the use of Intelligent Transport System (ITS) Technology.

The $1 billion project to create an iconic gateway to Western Australia is Perth’s biggest ever road infrastructure project and was designed to improve the safety and efficiency of one of the state’s most important transport hubs.

A.D. Engineering International’s continuing partnership with DownerMouchel and Main Roads WA is recognition of our high quality products, reliable performance and commitment to our clients and the community. We have already supplied a large number of variable speed limit signs, radar speed displays and transportable variable message signs and we are in the process of designing and manufacturing 17 large variable message signs to be installed across this project.

We have extensive experience with projects of this nature, and we have the capabilities and resources to meet customers’ specific requirements. Our work includes the whole process from design and manufacture to installation and maintenance, plus on-going support when required.
