After years of planning and changes, work has started on the centrepiece of the Gorge redevelopment and the final stage will go ahead next year.

Gorge Advisory Committee chairman and Launceston Deputy Mayor Rosemary Armitage said the project would make a big difference to Launceston's best known natural attraction.

Ald. Armitage said the inclinator would improve access for people with a disability and the new viewing platform would give the Gorge a "wow factor" by visitors having the best possible view.

She said the second stage of the $1.5 million project - sealing the viewing platform track and realigning the car park - should start in March and be ready by July.

Despite the project being proposed for years, she said it had not been delayed because it was built as money became available.

New steps have already been laid behind the cafe, where the viewing platform will be built.

"It will make the Gorge much more accessible ... it is intended to provide equality of access for everybody," she said.

"Your first aspect of the Gorge will be looking down to the swing bridge and that will give it a "wow factor".

"It's going to be great, we hope it will improve the experience for locals and visitors.

"At the moment it's difficult to get in and out of the Gorge."

Ald. Armitage said the inclinator, an inclined lift, would have a 42m travel with three stops via the cafe and carry 10 people travelling at a fast walk.

It was expected to either have an attendant, or an attendant could be summoned.

She said the viewing platform would have an "organic" feel, or blend into the Gorge surrounds, have 120sq.m of space, have a concrete roof and timber screens and an inclinator waiting area.

The view would include the pool, First Basin and the suspension bridge.

Ald. Armitage said work next year on the new access path, coming off the car park where the barbecues now are, would be covered in asphalt and the carpark realigned to encourage access through the new entrance.

She said the car park work would also improve traffic flow and safety and include a bus stop.

The existing 150 spaces would be retained.
