1 Rocky I Bridge Installation Park Butte Trail June 2005

2 The Plan The Park Butte Trail has over 8000 visitors of all ages from June through September. Project Objectives:  1. Provide a safe bridge over Rocky Creek during the peak summer season.  2. Bridge to be removed for the off-season to avoid heavy snow pack, uncertain stream flows, and flood events.  3. Bridge component weights to be within the capability of a type 3 helicopter (Hughes 500), approx. 1000 lbs.  4. Annual bridge flight time, assembly, disassembly and storage can be accomplished in two days or less.
