People travelling to Bruny Island around the Royal Hobart Show public holiday are warned that peak ferry use from Kettering typically occurs on Wednesday evening and Thursday morning.

Department of Infrastructure, Energy and Resources Secretary, Norm McIlfatrick, said today that occasionally there is a longer wait and a traffic queue forms in Ferry Road.

"We're encouraging motorists to consider travelling during non-peak times," Mr McIlfatrick said.

"Permanent Keep Clear zones are marked to assist residents' to access their driveways," 

"Motorists should only stop in Ferry Road where it is possible for local traffic to pass".

Mr McIlfatrick urged all those queuing for the ferry to obey all markings and signage and respect the rights of Ferry Road residents.

"Quite apart from any other considerations, these measures are being introduced to ensure everyone's safety," Mr McIlfatrick said.

"The Bruny Island ferry service is an important Government investment which connects an island community to jobs, services, and their fellow Tasmanians.

"The Government provides $640,000 each year to subsidise fares.

"The Department is also investing $8 million in improving Ferry Road and for the Kettering Waste Water Treatment Plant.

"The upgrade will provide better queuing facilities, which will make life easier for local residents. The Ferry Road upgrade is due for completion in mid 2014."

Mr McIlfatrick said that roads works to seal the existing gravel road surface along Bruny Main Road from the southern junction of William Carte Drive to the southern extent of the Alonnah 50km/hr speed limit were about to start.

"This is a $700,000 state funded project that will improve the safety of the road for local residents and tourists," Mr McIlfatrick said.

"Road works will be structured to keep delays to a minimum especially during peak ferry commuter times, however extra time should be allowed for travel during the construction period."
