Opening and evidence limits
The Liaoning provincial government reported on 16 October that the New Yalu River Bridge between Dandong and Sinuiju formally opened on 15 October. Xinhua’s Japanese-language photo report shows a truck on the bridge that day. The opening and an individual crossing are documented; routine customs operations, vehicle counts and freight volumes are not.
Xinhua reports that construction began in December 2010 and finished in October 2014. The 2026 opening is therefore a separate stage, not new construction. The gap between physical completion and use is a testable institutional factor for the transport model; these reports do not establish its cause.
Record AMU-20261016-001 counts one official opening event dated 15 October and first seen 16 October, not a unit of freight flow. Customs series, operating schedules, repeated crossings and comparison with the old bridge are needed. Model coefficients and calibration are unchanged. Hidden coordination is unestablished.
