Cardiff employs a bilingual street naming policy, particularly in the city centre, core routes, and Cardiff Bay area, where both Welsh and English names are displayed on street signs.
For new streets, the policy favours Welsh names that reflect the area’s heritage and history.
Existing street names in residential areas are generally maintained in their current language.
