If you’re going to visit Yellowstone National Park this weekend, expect some delays. The National Park Service is rerouting traffic around the Old Faithful Overpass Bridge in order to evaluate its condition.

While travelers will still be able to access Old Faithful and the Upper Geyser Basin, the Park is asking travelers not directly traveling to Old Faithful to use alternate routes to avoid delays. Road status updates can be accessed through the park’s website, or by texting “82190” to 888-777.
