The specific opening time of Changchun-Tonghua high-speed railway has not yet been determined. According to the information released before, the high-speed railway from Changchun to Tonghua is in the process of design. It is estimated that it will take one year to complete the design and exploration, then another year to carry out land acquisition and pavement treatment, and then start construction, with a construction period of 3 to 5 years. Therefore, under normal circumstances, the opening time of Changtong high-speed railway should be after the completion of design and construction, which is about 5 years.

However, it should be noted that the above progress may be affected by many factors, such as project progress speed, policy adjustment, technical problems and so on. So this is only a rough time forecast, and the specific situation may be affected by the actual situation.
