Motorists are advised to be aware of changed traffic conditions on the M1 to take effect on July 5 as an upgrade continues between the Kariong and Somersby interchanges.
The two existing M1 northbound and southbound lanes will shift to the right towards the central median for about two kilometres, between the southern end of the project and Wisemans Ferry Rd.
New work areas will also be set up on the northbound M1 exit ramp to Gosford and the southbound M1 entry ramp to Sydney.
The maximum load width on the northbound exit ramp to Gosford will be 6m and maximum load width on the southbound entry ramp to Sydney will be 5.1m.
Additionally, at the northern end of the project, the two existing northbound lanes will shift to the right towards the central median for about four kilometres from just north of the Gindurra Rd Bridge and return to the original alignment south of the Peats Ridge exit ramp.
Work to prepare for these changed traffic conditions around the Kariong interchange is currently underway.
The changed traffic conditions are expected to be in place until October and speed limits will remain at 80km/h.
