Plans to build a visitor centre overlooking the old Military Road at the rest and Be Thankful, have received the backing of motorsport legend, Sir Jackie Stewart.

The military road was built in the 18th century but has recently assumed an important new 21st century role acting as a diversion route when the A83 has been frequently closed by landslides.

Renowned for its 400 feet gradient and hairpin bends, the military road below the current A83 attracted leading international drivers including the late Scottish world champion racing driver Jim Clark until its condition meant only select events could be staged after 1970.

The proposed Rest and Be Thankful Heritage Project would celebrate the road’s link to Scotland’s rich motoring history. The centre is planned to include a cafe and arts spaces within a contemporary building. The project is the brainchild of Douglas Anderson, the man responsible for the return of the Monte Carlo Classic Rally to Scotland, back in 2011.

It has also received support from former world champion, Jackie Stewart, who raced the famous hill climb events which were staged by the Royal Scottish Automobile Club on the road in Glen Croe.

Project directors hope their plans will breathe new life into the popular stopping place and bring tourism spend and jobs to local communities.

Mr Anderson said “The Rest and Be Thankful has great significance in motorsport terms because of the famous hill climb races. It was seen as the ultimate test for drivers in many ways because of the steepness and conditions and many greats like Jackie Stewart raced there.

“The idea is to mark that connection within a permanent exhibition space but the project itself is more. The building will be a multi-use facility which could be used by the local community for film, business and cultural events and there will also be retail and a restaurant area."

The proposed building would he at the summit of the glen, already a favourite stopping place.

Meetings with officials from Loch Lomond and the Trossachs National Park, VisitScotland and Transport Scotland have been positive, according to the developers.

Sir Jackie Stewart, who raced the 1400 yard course in a Ford in 1961, believes Scotland is missing such a landmark to commemorate its proud place in global motorsport.

“The top of the Rest and Be Thankful is a beautiful setting with breath-taking scenery. It would be a tourist attraction to have such a facility as is being proposed and it would provide an opportunity to bolster Scotland’s great motor racing heritage and successes around the world which have been going on for a very long time.

“In Scotland, we don’t do enough of this.

“It would also be a nice place for people to stop and have a refreshment while driving around the highlands of Scotland. I am sure it would be excellent for tourism as well as for the Scots.”

The glass-fronted building will accommodate adequate parking and may also provide respite for diverted drivers if the A83 major road, running above it, succumbs to further landslips.

Designers Chris Twaddle and Gary Kennedy believe the attraction, which is now canvassing support for feasibility funding, is respectful of the natural beauty of the site.

“We wanted it to be sympathetic to its context but we also wanted to frame the view and accentuate the natural amphitheatre of the valley. We feel it is subtly quiet but also visually exciting,” said Gary Kennedy.
