Silver Bridge in 2018.

The National Park Service announced that the Silver Bridge in the Grand Canyon will be closed immediately due to structural concerns. Hikers use the bridge near Phantom Ranch. 

Now, those on the Bright Angel Trail will have to take a 1.5 mile detour to the Black Bridge in order to cross the Colorado River.

Phantom Ranch on the North Kaibab Trail will remain open, as will Bright Angel Campground.

There is no estimated time of repairs for the bridge.
