Boise Greenbelt section to close for months as Expo Idaho project continues
Ada County announced Monday that a popular section of the Greenbelt will close this fall and winter, affecting “hundreds of people who use this section” on a daily basis.
Beginning Sept. 2, part of the Boise River Greenbelt behind Expo Idaho will close for construction, according to a county news release. Ada County said the quarter-mile section stretching from the Boise Riverside RV Park to the Plantation Island Bridge won’t reopen until January.
The Marigold Street parking lot will remain open to the public, officials said.
The closure will allow construction at Expo Idaho to proceed as the county moves forward with its plan to modify that area of the Greenbelt to incorporate it into The Park at Expo, a 45-acre park planned for the county property containing the abandoned Les Bois horse racing track and outbuildings next to Expo Idaho at 5610 N. Glenwood St. and 5121 N. Alworth St, the Idaho Statesman previously reported.
“We love and appreciate this section of the Boise River Greenbelt as much as everyone else,” Josh Brown, Ada County senior project manager, said in a statement. “We know this is going to be a hassle for a lot of people who use this short thoroughfare every day.”
Brown said that once the Greenbelt reopens, this section will go past “spectacular wetlands, nature trails and the new playground park pavilion.”
Other plans for the new park include an all-wheel sports area, athletic fields, sports courts, an event space, a food truck pod, gardens, pavilion and a community plaza.
No traffic, including pedestrians and cyclists, will be allowed through until construction is complete. The county asked Greenbelt users to avoid the area or find an alternate route.
