Double Tennis Ball Intersection Design (Roe Hwy & Berkshire Rd)
Built as part of the Gateway WA project, the Roe Berkshire interchange delivered an innovative design providing the safest possible road environment for road users. This interchange incorporates a 'double tennis ball' intersection design which is the first of its kind in Australia. The intersection manages impact angles and / or speeds to be within survivable limits for vehicle occupants. This design occurred as a result of a multi stakeholder Trauma Review Group being established, as well as excellent innovative design work by the project team.
