About this file
This is a Questions and Answers document for Project No. ID FLAP KOOTEN 8450(1), Yellowstone Trail Road, Segment 1. The document addresses three technical questions regarding temporary roadway rockfall protection measures, specifically Mobile Rockfall Barriers (MRB), dated October 29, 2026.
The questions and answers clarify contractor obligations for rockfall protection installation. Regarding station ranges in Table 269-1, the MRB must extend at least 50 feet beyond active scaling or other upslope work areas; the contractor's means and methods will dictate the exact length of active work areas. On whether a single MRB can be relocated between station ranges or if both ranges require simultaneous protection, the answer specifies that temporary roadway rockfall protection needs to be in place during all work activities listed in Table 269-1. Regarding the 180-foot length specification on Sheet I.5, it is not a minimum required length but illustrative only; the MRB length will be determined by the contractor's means and methods and must extend at least 50 feet beyond active scaling or other upslope work areas. All three responses were provided on October 29, 2026.
