Tamar River Cruises has closed for a month while the City of Launceston progresses the second and final stage of an upgrade to the boardwalk.
On Thursday contractors worked to raise the Tamar River Cruises office and refurbish the old and worn timber structure.
City of Launceston general manager Robert Dobrzynski said the work was progressing “with no major issues”.
"As well as the recycled plastic decking, we have installed new timber joists and new steelwork,” he said.
He said the project remained “on budget and on schedule."
Tamar River Cruises is likely to remain closed until work is completed around July 1.
Managing director Alfred Gude said winter was a quiet time, and the closure would not see a significant financial loss to the business.
He said June was often the time when the ship was put on the slips for repairs and refurbishment.
Mr Gude praised the council’s investment in the boardwalk.
