Work has started on a dedicated pathway linking Canberra's city centre to Parliament House.

The 3.5 kilometre guided path will include 13 interpretive signs, mapping a route from the Jolimont Centre in the city, across Commonwealth Avenue Bridge to Federation Mall.

"It goes up through the nice woodland, that's actually just tucked between where the Electoral Commission building is and Federal Parliament," said ACT Territory and Municipal Services Minister Shane Rattenbury.

"There's a lovely little bit of remnant woodland in there and so it'll take walkers through there and straight up to Parliament House."

Mr Rattenbury says the signs will make the journey easier for locals and tourists.

"The new signs have been developed to complement other recently completed interpretive signage around Lake Burley Griffin which encourages people to access the tourism, cultural and entertainment facilities in the area and ultimately guides them to Parliament House," he said.

"The signage also includes interpretive information about cultural institutions around the lake and the history of the area."

Mr Rattenbury says the project will also aim to fix up the existing paths.

"This project was initially identified by [former Australian Greens leader] Dr Bob Brown, who as a regular visitor to Canberra often walked from his accommodation in the city to Parliament House and realised how badly signposted it was," he said.

The $200,000 project is being jointly funded by the Federal and ACT Governments, with the Commonwealth contribution a gift to Canberra in its centenary year.

The project is due to be completed in September.
