Washington County commissioners Tuesday voted for the emergency removal of the historic but crumbling Rock Island Swing Bridge.
"This structure is very far gone and much of it is beyond repair," Wayne Sandberg, county assistant engineer, told commissioners.
Their 5-0 vote means that Washington County now will work with Dakota County for complete removal of the bridge from the Mississippi River unless someone comes forward with money to save a portion of it for pedestrian, fishing or other recreational uses.
The National Park Service wants to preserve the west portion of the bridge as a part of the Mississippi River Regional Trail or as a lookout, and has been working with the counties toward that end. The bridge is within the 72-mile Mississippi National River and Recreation Area.
"It's not over yet," said Denise Niedzolkowski, an NPS spokeswoman in St. Paul.
Engineers from Washington and Dakota counties say that unless the NPS finds money for preservation, demolition could begin by March. The counties inherited the bridge as tax-forfeited property in 1999, when vehicle traffic ended, and see it as a liability.
The bridge spans the river between Inver Grove Heights to the west and St. Paul Park to the east.
On Tuesday some of the commissioners condemned attempts to save the bridge after Sandberg showed them photographs of decaying beams, piers and other structural elements. Although built well at the beginning, he said, the bridge suffered from years of patchwork maintenance.
