Look for enhancements at the Les Schwab Amphitheater this summer.  Construction got underway this week.  The goal is to make the amphitheater more accessible to accommodate anyone with a disability, and to make the stage bigger and sturdier to attract more performers.  Designers say the stage upgrade will feature what they’re calling a minimalist design, with pine accents to accentuate Bend’s sawmill history.  They’re also adding an extra wide pathway that will span the entire venue and the screens onstage to accommodate anyone with a disability.  R & H Construction of Bend is the general contractor for the project.  It’s expected to be completed by mid-summer, just before the start of the annual concert seasons.
