Yes, yes.
California's first wildlife overpass isn't even finished yet – but mule deer are already using it.
Cameras captured three mule deer casually walking across the structure just hours after construction crews wrapped up work for the day.
The crossing spans a dangerous stretch of State Route 97 in Siskiyou County, near the Oregon border. Between 2015 and 2020, more than 50 deer and 16 elk were struck and killed by vehicles along this section of road.
Now wildlife appears to be embracing the solution before humans have even completed it.
The bridge is California's first dedicated wildlife overpass. Once finished later this year, it will provide a safe route over the highway for animals including mule deer, elk, black bears, mountain lions, and gray wolves.
The overpass is roughly 100 feet long and 140 feet wide, making it feel less like a bridge and more like a natural piece of landscape suspended above the road.
But the bridge itself isn't the entire solution.
Wildlife experts say the most important feature may actually be the miles of 8-foot-high fencing being installed along the highway. The fencing helps guide animals toward safe crossing points instead of allowing them to wander onto the road.
The need is significant.
Researchers estimate drivers killed more than 48,000 mule deer across California in 2023 alone. Vehicle collisions accounted for more than 10 percent of the state's mule deer population that year.
Wildlife crossings have become increasingly popular because they protect both animals and people. Studies have shown they can dramatically reduce collisions while reconnecting habitats that highways have fragmented for decades.
The fact that deer are already using the bridge is an encouraging sign.
