Sanghwa-ro
Overview
Sanghwa-ro is one of the road names used in South Korea's road-name address system, a name formed by combining the proper noun 'Sanghwa' (祥華·上和, etc.) with the road-class suffix 'ro'. Under the Road Name Address Act, roads are assigned names and buildings are assigned road names and building numbers, and 'Sanghwa-ro' likewise corresponds to a road name designated and publicly notified through such legal procedures. Given that roads with the same name may be distributed across multiple local governments, it is more accurate to understand Sanghwa-ro not as a proper noun referring to only one specific place but as a group of cases to which road-naming principles have been applied.

Position in the road-name address system
After deciding to introduce road-name addresses in 1996, South Korea carried out phased reorganization and fully implemented road-name addresses on January 1, 2014. After a period of parallel use with the existing lot-number addresses (dong and lot number), road-name addresses have now become fully established as the legal address. Road names such as 'Sanghwa-ro' are registered in the National Address Information System (Road Name Address Guide System) and managed as road sections, road names, and building number information; this data is commonly used in various fields such as administration, mail, firefighting, delivery, and navigation.
Composition and origin of the name
Road names originate largely from natural place names, humanistic place names, historical and cultural elements, and the names of people. The element 'Sanghwa' also often comes from an old place name or village name of the relevant area, or from a person from the region. In practice, many local governments designate a person's name as a road name to honor a figure representing the region; representative examples include cases where the names of people deeply connected to the region, such as the poet Yi Sang-hwa (李相和) or the painter Na Hye-seok, are used as road names. Road names derived from personal names in this way follow the structure of 'full name + ro' or 'pen name (ho) + ro'.
Road class and scale
According to the Enforcement Decree of the Road Name Address Act, roads are classified by width into daero (40 m or more), ro (10 m or more and less than 40 m), and gil (less than 10 m). Therefore, 'Sanghwa-ro' is a name given to a road with a width of 10 m or more and less than 40 m, and it generally performs an arterial or auxiliary arterial function of about two to six lanes in each direction. A road name must have clear start and end points, and if it is too long to manage, it may be divided into sections and given separate road names.
Designation procedure and management
The designation of road names follows a procedure in which the mayor, county governor, or district office head drafts a plan in accordance with the road name designation ordinance and the road-name address work processing regulations, collects residents' opinions, and decides and publicly notifies the name after deliberation by the Road Name Address Committee. A publicly notified road name is reflected in road name signs, building number plates, and the electronic road-name address map, and when a road is newly established, abolished, or changed, the guidance facilities are updated along with a change notice. When the same name exists in multiple regions, as with Sanghwa-ro, the address notation uses the full structure of 'si/do + si/gun/gu + road name + building number' to prevent confusion.
Use and utilization
Road-name addresses are widely used as basic identifiers indicating the location of buildings, in mail delivery, emergency dispatch, location-based services (LBS), real estate registration and public registers, and tax bill delivery. Addresses written as 'Sanghwa-ro' are also recognized at the road-section level in navigation searches and map services, and building numbers follow the rule of being assigned along the road from the starting point toward the endpoint.
Latest trends
In 2024–2025, road-name address policy is focusing on digital transformation and precision. First, the expansion of object addresses (facility addresses) is progressing rapidly, with addresses being assigned to electric vehicle charging stations, bus stops, public restrooms, outdoor unmanned stores, etc., and object addresses are also being additionally registered in existing road-name sections including Sanghwa-ro. Second, as indoor addresses and 3D spatial information are combined in pilot applications, the foundation for indoor navigation and delivery automation is being established. Third, the opening and linkage of road-name address data is being strengthened, work continues to ensure consistency between public APIs and private map services, and replacement of old road name signs and improvement of address guidance for the elderly and vulnerable groups are being carried out in parallel. Fourth, from the perspective of disaster response, as awareness grows that the accuracy of road-name addresses is directly linked to securing the golden time for rescue, local governments are conducting error correction and updating of road-section data as a regular annual task. Along with this, Korea's road-name address model is spreading through overseas export projects, and several countries are benchmarking the Korean-style address system.
