Flooding of the Lake Monger shared path would go when the new concrete path was completed, Cambridge Town Council Parks Co-ordinator Ross Bowman said.
The concrete path was three metres wide and raised slightly above the surrounding grass to stop it being flooded in winter wet weather and collecting debris.
Concrete was used because it was more durable than bitumen, cheaper to build and maintain.
It cost between $150 and $200 a lineal metre.
Two stages had been done, from the city end around to the bowling club.
The next section from the freeway pedestrian overpass to the end of Dodd Street would begin in a few weeks time.
The last section from the bowling club to Dodd Street was due to be done in November-December.
The path in this section would be moved about 50 metres from the lake and raised to prevent it being flooded in winter. The edge of the lake would be rehabilitated under the long-term management plan for the reserve to improve the water quality and conditions for the native species.
The shared path parallel to Gregory Street from Dodd Street – part of the NW23 on the Perth Bicycle Network — through the bowling club car park to Lake Monger Drive was part of another program to improve the bike path network, as was the stretch of new path along the south side of Lake Monger Drive to Northwood Street.
The concrete was coloured marigold to get away from boring grey and because it blended better with the bore stains, a significant problem with the water in the lake.
Grass was being planted along the edges of the path, Mr Bowman said.
