A887 starts at the small town of Invermoriston on the banks of Loch Ness and heads west into the Northwest Highlands. It travels through the valley named Glenmoriston and parallel to the River Moriston before crossing the flowing water near Drundreggan. The Torgoyle Bridge was first built by Thomas Telford in 1811. After being destroyed during a flood in 1818, the three-span stone bridge was replaced in 1823 based on a design by Joseph Mitchell.
