UPDATE: The Rock Island Arsenal has re-opened the Rock Island Viaduct and Rock Island
Gate for normal operations.
Rainwater gathering near the Rock Island entrance to the Rock Island Arsenal has closed the viaduct.
The Rock Island entrance to the Arsenal also is closed as pumps cannot keep up with the water.
The Arsenal is opening the Davenport gate to people that have passes to get on and off the island. No word on when the Rock Island Arsenal will be reopened.
