It’s a popular vacation spot in Central Oregon and road construction and facility improvements are affecting is availability. Key attractions at Newberry National Volcanic Monument will open on a delayed schedule this season because of construction and facility repairs. Road construction on Highway 97 just south of Bend will create detours for people going to Lava Lands Visitor Center. These detours will be in place during much of the summer. Also affected: Lava River Cave is closed for site re-construction in May and June.
