Access to the Waterfront West/Shapinsay slip car park in Kirkwall will be restricted for a short period on Wednesday evening this week (10 January) while work on the Council's flood prevention scheme continues.
The latest stage of the scheme will see testing of flood gates in the vicinity.
As a result the Waterfront West/Shapinsay slip car park will be closed between 20.00 and 23.00 with no vehicle access in or out during this time.
The work has been scheduled to minimise as far as possible disruptions to pier users, ferry traffic and general public.
Pedestrian access will be unaffected by these works.
Construction of Kirkwall's flood defence scheme began along the central shoreline in February last year.
The scheme has seen the construction of a minimum 1.1 metre high uninterrupted flood barrier running from Ayre Mills to St Catherine's Place roundabout, which will help to protect low lying parts of central Kirkwall against storm surge flooding.
The £1.75m project has been 80% funded by the Scottish Government and was required under the Flood Risk Management Act.
The work has been carried out by local building and construction company Andrew Sinclair Ltd.
