Skagway is a small coastal city in southeast Alaska that became a gateway to the Klondike during the 1896 gold rush. Skagway is now a popular cruise ship destination and launching point for the historic narrow-gauge railroad between Skagway and White Pass Summit, which is a touristic attraction. The cruise ship dock and railroad are located at the base of the steep hills forming the fjord where there are two very active rockfall chutes.
Various rockfall protection measures have been installed at this site over the past 20 years, including cable net draped-attenuators, a 15 year old RX-050 (500 kJ) rockfall barrier, and modern rockfall Attenuator (ATT-80) utilizing SPIDER S4-130 as the structural mesh. The latest installation of an RXE-8000 (8,000 kJ) is replacing the old RX-050 (500 kJ) that has been overwhelmed by beyond maximum impacts and repaired multiple times.
Challenges included anchorage and support ropes crossing an active rockfall chute and a tall launching cliff directly above the barrier location requiring elevated post base supports (foundations).
