Bridge Lifts

This graph and picture of the channel from the Official CRC Navigation Fact Sheet (2MB pdf) pretty well define the problem. All barge traffic is low enough to fit under the high spans of the I-5 bridges, but the high spans do not line up with the swing span on the railroad bridge. During adverse conditions, barges must use the lift spans.
If this problem were solved, you can see from the graph that nearly all bridge lifts on I-5 would be eliminated.
