A pre-Christmas start date for the £894,000 commercial and pleasure marina to be built at Sutton Bridge is expected to be announced soon.
Some pleasure moorings were lost from the original scheme, which was costed at £915,000, because delays over buying land meant cash earmarked from a European budget was lost when the deadline for spending it expired.
Lincolnshire County Council, which is steering the project, says it will provide 48m of commercial mooring, a 60m town quay and 60m of double-sided leisure moorings.
Those “wet-side” works are out to tender and the deadline for bids is next Tuesday.
“Dry-side” works include a car park, footpath and utility services.
The project won’t be completed until next summer because wet-side works can only be done between certain tides.
A county council spokesman said: “The marina has been designed in a way so that a further phase of leisure moorings can easily be added at a later date subject to funding and business case.”
The county council says the project will provide a “significant boost” to the local economy, benefiting businesses and residents alike.
