Works on the latest stage of the $1 million Parnkalla Trail wharf precinct upgrade has faced delays but is expected to be finished by the end of April.
The latest stage, between the grain silos and the fishing jetty will include a boardwalk, balustrades, fencing, footpath surfaces, street furniture and a shelter.
Main works for the stage began in November and was scheduled to be finished at the end of January.
However Port Lincoln City Council's community assets and civil projects officer Sebastian Carr said there were some delays, including with the installation of the fence piles and the detection of asbestos in the soil.
"We took out 240 tonnes of contaminated soil and brought in new, clean fill, mobilising contractors from Adelaide which caused a delay in the run up to Christmas," he said.
Mr Carr said during installation of the piles for the boardwalk there was a need to extend some of the piles to achieve safe load ratings due to varying soil conditions.
He said the boardwalk should go into place withing the next two to three weeks and works on the stage was expected to be completed by the end of April.
Once work on the stage is complete the council will look to move on quickly to the next stage, which will be from the Troubridge Ferry dock and past the truck marshalling area.
"With additional truck movements it's put pressure on pedestrian safety," he said.
"We are working closely with Flinders Ports and Viterra to try and ensure the final design ensures pedestrian safety."
