On behalf of the Organizing Committee, I am sincerely pleased to invite you to the 7th International Symposium on Transportation Soil Engineering in Cold Regions (Transoilcold 2025), held at Songdo ConvensiA in Incheon, Korea. The International Conference is held on-site during September 17-20, 2025.

The main objective of this conference is to provide a current issue of design, construction and operation of transportation infrastructure in Arctic and cold Regions.

Moreover, the conference covers a number of topics in geotechnical engineering including geophysics, slope stability, soil dynamics, modelling, geosynthetics, foundation, geoenvironmental technology, underground construction, maintenance, and disaster prevention.

I would like to express my deepest gratitude to all the participants in this event, and special thanks to the Speakers for their commitment and dedication. I hope you to have a very pleasant and meaningful time during the event, and look forward to learning from your productive insights.
