The stricken bridge was on the Kansas City district between Kansas City, Mo., and Moberly, Mo.
NS is diverting traffic to other railroads and the incident is resulting in shipper delays in the Kansas City area of from 48 to 72 hours, railroad officials say.
As the situation was being assessed Wednesday, NS officials had no estimate on when service on the line would be restored.
Brunswick Emergency Management Director Brent Dickerson reported Tuesday that for safety reasons and to allow NS crews to operate uninterrupted, there were barricades on the river to keep boaters away from the collapse area, according to CentralMoInfo.com.
