The current Kibagie Roundabout lies at the northern end of the Clackmannanshire Bridge road, and is the new end of the A876 on the A977. It is a new junction built slightly offline to the west of the old A977 route, and therefore curving the A977 to meet it. This gives a simple 3-arm layout, with the A977 running north-south and the three-lane A876 approaching from the south west.
Prior to the construction of the Clackmannanshire Bridge, there was another Kilbagie Roundabout a short distance to the south at the entrance to the Tulliallan Police Training College. This didn't just serve the police, however, it was also the start of a short section of the A985, which headed north west to meet the A907, bypassing the old crosssroads at Gartarry. The old line of the A985 survives, but is gated and not open to traffic. The roundabout has now been removed, and the junction is a simple T junction for access to Tulliallan.
