Project Description

The M1 Productivity Package consists of three projects including:

Kariong to Somersby (and Kariong interchange) — widening of an 8km section of the M1 Pacific Motorway between the Somersby and Kariong interchanges from four lanes to six lanes and upgrades to three of the four interchange ramps that provide the main arterial access to and from the motorway to the Central Coast Highway and the city of Gosford. This excludes a 1.5km section on the southbound carriageway between the Kariong interchange southbound exit and entry ramps;
