THE retail park being built on the outskirts of Haddington should be treated as “an opportunity not a threat” to the town centre, the Provost of East Lothian has said. Haddington Retail Park, on the western edge of the town, is due to open later this year and will include The Food Warehouse, Home Bargains, Costa Coffee and a petrol station. Aldi will also swap its town centre site off Whittingehame Drive for a new, larger store in the retail park, with the occupier of a fifth unit yet to be revealed. The retail park will have nearly 300 free-of-charge parking spaces and is also within walking distance of hundreds of new homes being built at nearby Gateside and Letham Mains.
