This year’s flood event on the Boise River dramatically affected the concrete abutment of the Greenbelt Bridge on the Plantation Islands owned by the Idaho Foundation for Parks and Lands. With the possibility of a failure of the abutment and at the urging of the Ada County Highway District, Ada County and the Idaho Foundation removed the Bridge to prevent greater damage should it fall into the water.
Current weather models show the possibility of a similar winter next year and there always exist, the chance of future flood events on the Boise River. A long term solution will be needed for the placement of a new abutment to hold the Greenbelt Bridge.
Until low water in the Boise River allows a complete inspection of the structure, the Bridge will remain removed. The structure needs to be examined to determine if protection can be provided from high stream flows or if the current location is unsustainable from the erosion effects of a 9,000 + CFS river flow. A relocation of the Bridge, if that is necessary, will involve multiple partners, to include, Ada County, Army Corps of Engineers. ACHD, Flood Control District 10, Garden City and the City of Boise.
The Idaho Foundation regrets the inconvenience of the lack of a crossing of the Boise River Greenbelt, but will work diligently with its partners on the Greenbelt to obtain a long term solution that is sustainable.

Safety remains a big concern as flooding along the Boise River is having a major impact on the city’s Greenbelt system. That flooding lead to the removal of a nearly 30-year-old bridge today. A and that’s not all. Boise Parks and Recreation has closed eight sections of the Greenbelt due to the high waters, with the mayor warning that people should stay away from the area altogether.
The area where the Plantation Bridge connected the Greenbelt to Plantation Island continues to be eroded by swift waters; leaving officials no choice but to remove the bridge, or risk it falling into the river. The Plantation Bridge has connected Plantation Island to the Greenbelt for almost 30 years. But, due to rising waters and unsafe path conditions, crews had to remove the bridge this afternoon.
“The path is undercut. So the pavement is there, but there is no soil underneath,” said Judy Peavey-Derr. The Idaho Foundation for Parks and Lands owns the bridge, along with the pathways on Plantation Island. “It’s going to be a while before people can get back on and use it again,” said Peavey-Derr. That’s because the Idaho Foundation, right now, doesn’t have the money to fix all of the pathways or pay for the reinstallation of the Plantation Bridge.
“Until the water goes down and we have the money to rebuild this section, we’re not going to be able to use the path,” said Peavey-Derr. Right now, estimations to fix the gap are in the thousands. “It’s going to be a major expense,” said Peavey-Derr. The Idaho Foundation sought out the help of Ada County to help pay to remove the bridge.
“It’s about anywhere between $16,000 and $20,000 is what it’s going to cost to move this bridge,” said Ada County Commissioner David Case. Case, because Ada County is under a disaster declaration, they were able to remove the bridge quickly using disaster funds.”We’re always willing to try and help out, especially with the Greenbelt,” said Case. “I mean this is part of what our public uses, and they use it heavily. So yeah, we’re going to be at the table talking with folks to see how we can get this fixed.”
