Cape Arago Lighthouse Bridge

Stuntzner Engineering & Forestry (Stuntzner) was contracted by Scott Partney Construction to provide design services for access, skyline and purchase analysis for logging equipment to remove the existing bridge spans and worker support walkways attached to Cape Arago Lighthouse which was undergoing renovation. Along with Scott Partney Construction, Stuntzner also worked with Billeter Marine (Contractors) to provide the shoring, access and demolition system design elements. Stuntzner’s knowledge of both forest engineering (logging systems) and civil engineering was utilized to facilitate removal of the bridge with standard logging equipment on one side and a constructed tower on the island side to provide lift. 

This project took place between November and February of 2012-2013 – not ideal repainting or working weather on the Oregon Coast!  The current bridge to the island where the lighthouse stands had been condemned and was scheduled for removal.  This, in turn, made it difficult to access and renovate the lighthouse.  The plan thus involved fixing the lighthouse first (primarily painting, replacing windows, sealing and repair) and then demolishing the access bridge to it.

Another key issue that had to be addressed was the fact that the site is of cultural significance. To avoid disturbing any of these areas, no purchases for the logging equipment locations could be placed on the soil, instead they had to be on rock outcroppings.

This U.S. Coast Guard property will be turned over to the Confederated Tribes of the Coos, Lower Umpqua and Siuslaw Indians.
