The trail IS open as of today.
We ran into Nathan, the city of Rogers guy in charge of the mtn bike trails (and ride park). He confirmed that the trails south of Walnut are open. He even added a bridge to connect the 2 southern sections while they worked.
The parking is at 1615 Pleasant Ridge Rd, at the lot there. You can access the southernmost section from there.
We got a map from https://www.nwatrails.org/trail/lake-atalanta/ (I am trying to get it uploaded) There are a few new link trails added to make it better for continuous riding.
Blues have some steep sections, with quite a few banked turns, so fun downhills. Great signage, at intersections, unlike Slaughter Pen, so you won't get lost.
We could only do about 5 miles.
The city website says the park will reopen this summer. Until then, enjoy the southern trails.
