Warringah Freeway Noise Walls

If the Warringah Freeway were built today, it would automatically receive noise walls along its entire length.

Since it opened in 1968, the volume of traffic in this corridor has increased steadily and carries more vehicles each day - noise walls are urgently needed.

North Sydney Council has repeatedly raised concerns with the State Govt (see Council correspondence below in Related Documents).
