GTX-D Y-Line Project Faces Uncertainty Due to Economic Feasibility Concerns

The proposed GTX-D Y-line, a high-speed rail project connecting Incheon Airport to Seoul and beyond, faces economic feasibility concerns, potentially jeopardizing its future. Concerns arise from the project’s overlapping routes with existing Seoul subway lines, potentially hindering its cost-effectiveness. The project’s overlapping route with Seoul Subway Line 5, combined with the use of existing capacity-limited Seoul Subway Line 9, could lead to a low benefit-cost ratio (B/C), raising questions about the project’s economic viability. The potential cost overruns, exacerbated by rising construction costs, further complicate the feasibility assessment. While the project’s potential benefits for Incheon’s infrastructure and transportation are recognized, these concerns may necessitate adjustments or revisions to the project’s scope or route plan.
