Independent Upper House MP Ruth Forrest is urging for a second bridge to built. "The community can now unite and focus on the important discussion.

After almost two weeks of traffic chaos a flood-damaged Tasmanian bridge has reopened but repairs could continue for weeks in other parts of the state.

The Bass Highway at the Cam River Bridge in the state's north-west was reduced to one lane in October after floodwater undermined a support pier.

Commuters became stuck for hours, particularly during morning and afternoon peaks, and concerns were raised about how the thousands of people living west of the bridge would access key services.

Now additional concrete strengthening between the bridge piers has been installed and both lanes have been deemed safe.

"The Tasmanian government thanks the public for their patience while the repairs were urgently completed," Infrastructure Minister Michael Ferguson said.

"We acknowledge the travel time delays and inconvenience caused by the lane closure.

"We also thank all those involved in supporting the community during the closure and repairing the damage as quickly as possible."

Call for second crossing:

The government was criticised for not giving enough information to residents about ongoing delays.

Independent Upper House MP Ruth Forrest urging for a second bridge to built.

"The community can now unite and focus on the important discussion around the second bridge over the Cam River," she said.

"This event has clearly demonstrated the importance of this critical infrastructure link and the need to ensure there is not a similar event in the future."

A new $18.8 million bridge over the river is being constructed to replace the existing bridge, but the government has not ruled out the possibility of a second bridge.

A reduced speed limit is in place and monitoring of the bridge's stability will continue, while additional bus services will also remain in place.
