The seasonal pedestrianisation of Tenby's walled town is about to begin again.
The walled town will be largely traffic-free from tomorrow (Saturday) to August 31, between 11 am and 5 pm daily.
The 2004 experiment permits some limited travel within the walled town subject to certain criteria being satisfied.
Access for emergency vehicles and services will be permitted, as well as access for medical needs and harbour use.
Special arrangements will be made to accommodate weddings and funerals, and concessionary car parking will be available in council-owned car parks for those denied the opportunity to use their own car park spaces.
The scheme will be supported by an enhanced park and ride service, which recently won two awards in the National Transport Awards, sponsored by the Wales Transport Research Centre.
Since November, elected members and officers of Pembrokeshire County Council have held three meetings with representative groups in an attempt to find agreement on how to deliver effective pedestrianisation for the walled town during the months of July and August.
This process follows two experiments undertaken in 2002 and 2003.
Pembrokeshire County Council's director of transportation and environment, Ian Westley, said: "The pedestrianisation experiment for 2004 has been improved by some very positive dialogue between representative groups and council officials.
"We are all hopeful that the concessions that have been made by all parties will result in a successful scheme for the coming summer."
