Which Boise roads, trails are closed because of wildfire? What to know
A wildfire burning in the Boise Foothills has closed a number of roads and trails in the region.
Firefighters with the Boise Fire Department were first dispatched to North Claremont Drive north of the Military Reserve on Monday shortly after 1 p.m., the Idaho Statesman previously reported.
As of 7 a.m. Tuesday, the Claremont Fire had scorched about 2,500 acres of land, according to a social media post by the Boise Fire Department.
By 2 p.m., the blaze had grown to 3,850 acres, officials said.
No structures have been lost and no evacuation alerts have been issued for residential areas. The cause of the fire remains under investigation.
However, residents have been told to avoid the at-risk trail system that weaves through the Boise Foothills.
Here’s what to know about closures.
Which Boise roads are closed due to wildfire?
The Boise Fire Department and the Bureau of Land Management have temporarily shut down a portion of Eighth Street where it becomes Sunset Peak Road.
“Eighth Street is closed above the Foothills Learning Center to allow for firefighting operations,” Boise Fire said in a Facebook post on Tuesday afternoon. “Please avoid the area and do not drive up Eighth Street, as there is an active wildfire and aircraft are dropping fire retardant.”
The U.S. Wildland Fire Service said Tuesday morning on Facebook that crews are focused “on securing Rocky Canyon Road and Eighth Street up to Boise Bridge Road.”
Which trails are closed in Boise Foothills?
The U.S. Bureau of Land Management’s Four Rivers field office issued an alert on Monday temporarily closing all “lands, roads and trails between Bogus Basin Road, Idaho Highway 21, and Boise Ridge Road” because of the Claremont Fire.
The affected area runs approximately 2 miles northwest of Boise and includes the Hulls Gulch trails, according to the Bureau of Land Management.
Are Ada County trails open?
The Ridge to Rivers Trail System is an “interconnected network of roads and trails courses” that links neighborhoods with public lands, the Bureau of Land Management said on its website.
Several of the trails along the Ridge to Rivers system that are managed by Ada County have been closed because of the wildfire.
How long will Boise Foothills lands remain closed?
The Bureau of Land Management expects the area to be closed until late Saturday, July 11, according to the alert.
What are wildfire-related health concerns?
Tens of thousands of wildfires happen yearly in the U.S., according to the National Interagency Fire Center.
When a wildfire breaks out, it’s important to reduce your exposure to smoke.
According to the Centers for Disease Control and Prevention, wildfire smoke can irritate eyes, noses, throats and lungs.
“It can make it hard to breathe and make you cough or wheeze,” the CDC says. “Children and people with asthma, COPD, heart disease, or who are pregnant need to be especially careful about breathing wildfire smoke.”
Here’s what the CDC says you can do to help stay safe during a wildfire:
- Set up a portable air cleaner or filter in a room closed off from outside air if possible.
- Use a respirator or mask if it’s safe for you to do so.
- Avoid using candles, gas, propane, wood-burning stoves, fireplaces or aerosol sprays.
- Keep pets safe by learning how to protect them.
- Keep track of fires and be prepared to leave.
- Pay attention to your health symptoms.
- Evacuate safely by following and practicing your plans.
