Pont Llanychaiarn carries the A487 across the River Ystwyth at Llanfarian. It is the closest classified road crossing to the river's mouth at Aberytswyth. It appears that the bridge is a historic stone arched structure, crossing the river with a single span, which has been widened by adding a curved concrete deck to the east side to provide a two-way road deck.
