A €6m upgrade for Howth Pier has been described as "badly-needed".
The funding for the Howth Middle pier redevelopment project, which has already begun, was included in the Government's July stimulus package announced last week.
A tender competition to find a contractor has ended, and the Department of Agriculture, Food and the Marine, will award the contracts soon.
The project will provide an extra 130 metres of berthing on the Middle Pier.
Fishermen will get a 1,600 square metre area behind the new pier to repair nets and service vessels.
The project is aligned with the overall department strategy to separate heavy fishing activity and industrial work from leisure activity as much as possible and ensure the health and safety of all users of the Fishery Harbour Centre.
The idea is to make facilities for more boats and easier berthing.
Councillor Jimmy Guerin said the work was greeted with a positive response.
"They had put in the application and were waiting for the funding for the work. The plans have been on for a while," he told the Herald.
"Happy days - the work is badly-needed for the dredging operation, which is hugely necessary in Howth, so it's very welcome.
"The Marine Department and the harbour master did a presentation to the Howth- Malahide area a year ago and they got great feedback."
Fianna Fail TD for Dublin Bay North Sean Haughey said: "I am delighted this project has been included in the July stimulus package.
"This project will not only enhance the pier as a fishery harbour but also Howth as a leisure destination.
"The project will employ 50 construction workers, which will have a huge knock-on effect on the local economy.
"Once completed, the berthing facilities will encourage increased fishing activity.
"As the heavier industrial work will be concentrated on the Middle Pier, leisure activity on the West Pier will be further facilitated."
