Navigation Warning - Grafton Bridge


Grafton Bridge, Clarence River
4 October to 31 October 2016


Vessel operators are advised that Fulton Hogan will be conducting pre-construction marine geotechnical drilling and investigation work for an additional Bridge over the Clarence River at Grafton. The works will commence on 4 October 2016 and continue for a period of approximately three weeks, finishing on 31 October 2016, weather permitting. Work will be carried out between the hours of 7:00am and 6:00pm Monday to Fridays, and 8:00am to 5:00pm Saturdays. The work will commence on the southern side of the Clarence River, and continue in a northerly direction adjacent to the current Bridge alignment, as indicated in the map below.

A 12 x 8 metre ‘dumb’ barge fitted with a drilling rig will be undertaking core sampling to assist with the new bridge design. The barge will display an all-round white light, and flashing orange lights to indicate its location at night.


Vessel operators are advised to exercise extreme caution when navigating in the vicinity of the works, and to pay particular attention to construction work vessels. Operators must reduce speed to 4 knots when within 100 metres of the work barge and minimise wash. Additional signage and navigational markers may be in place.

This navigation warning remains in place for the duration of the work.
