Approval Granted for the Revised “Metropolitan Transportation Improvement Measures” for the Busan Eco Delta City Development Project

내용

Busan Metropolitan City (Mayor Park Heong-joon) announced that the revised “Eco Delta City Metropolitan Transportation Improvement Measures,” which incorporates transportation system improvements in response to development around Eco Delta City, changing local conditions, and enhanced convenience for residents using public transportation, was approved yesterday (June 23) by the Ministry of Climate, Energy and Environment.

The Metropolitan Transportation Improvement Measures are a statutory transportation network development plan designed to effectively accommodate regional transportation demand and prevent traffic congestion arising from large-scale new town developments. Under the Special Act on Metropolitan Transportation Management in Metropolitan Areas, such plans are mandatory for development projects exceeding 500,000 square meters.

Following consultations with Korea Water Resources Corporation, the developer of the Eco Delta City project, Busan Metropolitan City submitted the proposed revision of the Eco Delta City Metropolitan Transportation Improvement Measures to the Ministry of Climate, Energy and Environment in September 2025. After review by the Waterfront Zone Development Committee, the ministry granted final approval for the revision on June 23.

This approval reflects the city’s updated transportation policies since the original approval in 2014 and includes plans to introduce the Gangseo Line Tram, a future-oriented transportation system for Eco Delta City.

Major revisions include replacing the Bus Rapid Transit (BRT) system, which had been included as the new transportation mode in the 2014 plan, with a new plan to introduce the Gangseo Line Tram (6.6 kilometers within Eco Delta City). This establishes transportation infrastructure connecting Daejeo, Eco Delta City, and Myeongji.

The Gangseo Urban Railway Line (2026–2034) is planned to operate as a tram-based transportation system extending 21.1 kilometers from Daejeo Station (Metro Line 3) through Eco Delta City and Myeongji International New Town to Myeongji Ocean City, with 25 stations and three depots.

In particular, incorporating the Gangseo Line Tram into the Eco Delta City plan removes obstacles to advancing the urban railway project that had resulted from limitations associated with the previous BRT proposal. The revision lays the groundwork for implementing the full 21.1-kilometer Gangseo Line Tram and is expected to serve as a catalyst for a major transition to new transportation systems throughout western Busan.

In addition, to address public transportation inconvenience experienced by early residents of Eco Delta City, the city introduced the Eco Nubi Bus service ahead of schedule in October 2025 and has been operating it ever since. To support this service, Busan Metropolitan City plans to establish a new public transportation subsidy program totaling KRW 5 billion over five years through 2029.

The Eco Nubi Bus currently operates two routes within Eco Delta City using six buses and will receive support for five years from 2025 through 2029.

Other components of the project, including roadways, connecting facilities, and the planned Eco Delta City Station, will remain unchanged from the existing development plan, while implementation entities and related arrangements have been updated to reflect changing local conditions.

Lim Kyung-mo, Assistant Mayor of Urban Innovation and Balanced Development, stated, “The approval of the revised Eco Delta City Metropolitan Transportation Improvement Measures marks the first step toward introducing the Gangseo Line Tram, a next-generation transportation system. Once the tram and the Eco Delta City Station on the Bujeon–Masan Line are established, we expect transportation inconvenience for residents to be significantly reduced and Eco Delta City to evolve into a cutting-edge future city.”
