In December 2001, Saltaire was designated a World Heritage Site by UNESCO. This means that the government has a duty to protect the site. The buildings belonging to the model village are individually listed, with the highest level of protection given to the Congregational church (since 1972 Saltaire United Reformed Church) which is listed grade I. The village has survived remarkably complete, but further protection is needed as the village is blighted by traffic through the Aire Valley, an important east-west route. A bypass is proposed to relieve traffic pressure. Roberts Park, on the north side of the river, suffered from neglect and vandalism but has been restored by Bradford Council. In July 2014 it was announced that planning officers had compiled a list of replacement front doors that were deemed to be "not in keeping with the buildings' historic status."
