Skulamus Junction lies at the eastern end of the village of Broadford on the Isle of Skye. It is the northern end of the A851, which leads south to the ferry port of Armadale, from where Ferries cross to Mallaig on the mainland. This makes it quite a busy junction, particularly in the summer months when the ferries are more frequent. The junction is a standard give way, which has been reprofiled to improve visibility. The A87 curves through the junction, and the A851 approaches at an acute angle, so it has been turned to meet the A87 squarer on to improve visibility.
Prior to the construction of the Skye Bridge, the main route across the island was the A850. However once the bridge opened the A87 was extended across Skye, and the volume of traffic increased, perhaps with a reduction on the A851 which suddenly became a less direct route to Skye as it still relied on a ferry. However, at the same time, the opportunity of a daytrip using the bridge and ferry to make a circuit became possible, so the volume of right turning traffic out of the A851 has probably increased proportionally.
