This week, the Regional District of Okanagan Similkameen (RDOS) said it’s undertaking a study regarding the historic Adra Tunnel, which is located above Naramata.
“A plan has been developed to clear debris in the tunnel, complete a rock structure survey and develop plans for stabilizing the tunnel,” said the RDOS.
“Any future reopening will be contingent on whether it is technically and financially feasible to do so in a way that is safe for trail users.”
The Adra Tunnel was closed in the early 1990s due to unstable conditions. Further, deliberately set fires in the tunnel in 2010 and 2012 destroyed the remaining timber supports, further deteriorating tunnel stability.
The 483-metre-long tunnel was originally excavated in 1913-14 as part of the development of the Kettle Valley Railway (KVR).
Rail operations ceased in the 1970s, with the province purchasing the KVR lands in 1990. The RDOS says the tunnel’s timber supports were deteriorating after rail operations ceased.
Crews will begin accessing the tunnel in mid-September.
“The RDOS believes the tunnel if reopened,” said Electoral Area E director Karla Kozakevich, “will bring long-term benefits to residents, tourists, and local businesses.”
