Llangollen's main car park is to be partially closed for about five days from next Monday.
The Market Street car park is being resurfaced and re-lined, according to Denbighshire County Council.
Cabinet Lead Member for Public Realm, Councillor David Smith, explained that the council has planned for around half the car park to remain open during the works in order to help minimise disruption.
"We expect this will allow for resurfacing and re-lining of the entire car park within the five days and we would like to thank people for their patience in advance," he said.
Lewis and Hunter Contracting Ltd will be undertaking the work on behalf of Denbighshire County Council and there are alternative car parks at:
* East Street
* Hall Street
* Mill Street
* Brook Street
* Llangollen Pavilion
