Crews have begun the long process of reconstructing Myra Canyon Trestle 3.
Clean-up and rock scaling work began last Thursday and is expected to continue until the middle of July after a rock slide in April did significant damage to the trestle.
Boulders as large as small vehicles came down the side of the hill and took out some of the underpinnings below the trestle deck.
According to officials with the Ministry of Environment, once scaling work is complete around the middle of July, crews will then begin the process of disassembling and reconstructing the damaged trestle.
"For safety reasons the trail will be closed from Trestle 2 to Trestle 4 during scaling activities," the Ministry of Environment stated in an email to Castanet News.
"The public will still be able to access Trestle 2 and 4 but will not be able to go beyond them."
The area of trail below the rail grade will also be closed due to a hazard of falling rock.
"For the safety of both the public and scaling crews, BC Parks is asking that people respect these closures."
Trestle 3 will remain closed through the duration of construction.
"The remainder of the Myra Canyon trail will be open to the public with access from Myra Station parking lot to Trestles 18 through 4 and Ruth Station parking lot to Trestles 1 and 2."
A bypass trail around Trestle 3 will be made available once rock scaling activities have concluded.
Total cost of clean-up and restoration of the damaged Trestle 3 is estimated to cost about $350,000.
