What's left today:
When the railway closed the central steel girder span was removed, but the rest of the viadcut remained. After the viaduct the railway would cross the road via a bridge just outside Balquhidder Station, but this bridge has been demolished since the road was made wider.
However, Kendrum Viaduct is now being used as part of a foot and cycle path following the old railway outside Lochearnhead. The central steel girder span has been replaced with a more modern one.
