This follows two separate roll-overs of a B-double on December 2 and a cattle truck on November 23, on the southern entrance to the Blackmans Point interchange work.

Traffic on the Pacific Highway has been diverted onto a temporary road around the area where the new interchange is being built.

The diversion allows work to continue building the interchange directly on top of where the existing Pacific Highway was. The new interchange is the largest on the project and includes two bridges and seven ramps that will allow traffic movements in all directions.

The interchange will be similar to the Oxley Highway interchange with a roundabout feature above the new highway.

A Roads and Maritime Service spokesperson said safety measures had been implemented at the site since the last crash (in November).

“Safety measures including radar activated speed signs have been installed in this area since the last crash and Roads and Maritime is investigating additional measures to improve heavy vehicle safety in this area,” the spokesperson said.

The 34 year old driver of the B-double was transported to Port Macquarie Base Hospital in a stable conditions following the December 2 crash.

Roads and Maritime will assist NSW police with any investigations into the crash.

On November 23 a cattle truck rolled over and blocked the highway for a number of hours.

When complete, the Blackmans Point interchange will become the northern connection for people travelling to and from Port Macquarie, and provide the main connection to Blackmans Point and the southern entrance to Telegraph Point. 

The existing access to Blackmans Point Road from the Pacific Highway is not affected by the diversion.
