I've been made aware of some upcoming road work which will cause major impacts to the cycling community due to road closures. First one will be on Happy Valley Road, just east of Bear Creek Road, for a slide repair. Anyone who's ridden this road knows what I'm talking about, metal trench plates over the road and some temporary concrete barriers adjacent to the slide. In order to repair the road, it will require closure starting July 15-October 31.

The other road closure I know about will be on Pinehurst Road, the "north" direction. Road will be closed from the Post Office to the county line (at Skyline) for a culvert repair.

The above link doesn't state the closure dates, but I know that it will be closed from the beginning to the end of the project.
There will be other repairs on other area roads which may or may not lead to closures, I'm not sure about those. Two on Alhambra Valley (west of Castro Ranch and east of Ferndale Rd), and one on Bear Creek Road (the area with the temporary concrete barriers). This summer will be busy with road closures, and some of these would cause major interruptions and detours to cyclists. Be advised and plan alternative routes!
