Police have reopened the Arthur Highway in Tasmania that runs from Sorell to Port Arthur on the bushfire-ravaged Tasman Peninsula.
Motorists are being asked to drive with caution, particularly between Sugarloaf Road and the Dunalley Bridge, with work crews still restoring essential services to the area.
Drivers of light vehicles who want to go south of Dunalley are being advised to detour via Sugarloaf and Fulham Roads to avoid lengthy delays.
Police say large vehicles, those towing trailers, service vehicles and tourist buses should stay on the Arthur Highway which has a speed limit of 60km/h.
They say motorists also need to be mindful of stock on the road due to the destruction of fences, particularly in the Sugarloaf Road and Fulham Road areas.
Peninsula residents were allowed to return last Friday.
Meanwhile, fire crews have made solid progress on consolidating containment lines around bushfires still burning ahead of higher fire danger conditions forecast for Thursday.
Tasmania Fire Service has issued a watch and act message for the uncontained 24,040-hectare Forcett blaze where 150 firefighters using 39 tankers and four aircraft continue working on the fire which has a 200km perimeter.
Firefighters had been strengthening containment lines around Bream Creek and Marion Bay and also at Lagoon Bay, but had to eventually pull out due to increased winds, TFS spokeswoman Shannon Fox said on Sunday.
"In Taranna, we've got a good, strong containment line in but we're working on looking after some hot spots that are within the already burnt out areas," she told AAP.
"What we are really trying to do is be prepared for Thursday when we expect fire danger ratings to increase again."
At Lake Repulse, fire crews consolidated containment lines to the south of Brown Mountain and New Zealand firefighters worked on containment lines at the Broad River Valley, Ms Fox said.
