Double Tennis Ball Intersection Design (Roe Hwy & Berkshire Rd)

Nicholls, G.

Design of Safer Roads

ARSC conference 2017

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.
