A safety warning has been issued ahead of work starting asking local people not to enter the Caerlee Mill site, with a series of additional safety measures added over the summer.
Russel Griggs, who chairs SOSE, said: “With planning permission and a proposed timetable now available, the local community and mountain bike industry can now start to see how our plans are going to become reality.
“We know it has not been a straightforward process, and we thank local people, the mountain bike sector and partners for their patience and support.”
He said the new centre would bring “high quality jobs” and “maximise the value” of mountain biking in the area.
Scotland Office minister Kirsty McNeill added: “I welcome this major step forward towards the mountain bike innovation centre in Innerleithen opening for business, bringing jobs and investment to the region and attracting riders from across the country and beyond to a world-class facility.”
