The Penkalas Bridge is a Roman bridge over the Penkalas (today Kocaçay), a small tributary of the Rhyndakos (Adırnas Çayı), in Aezani, Asia Minor (Çavdarhisar in present-day Turkey).

The 2nd-century AD structure was once one of four ancient bridges in Aezani and is assumed to have been the most important crossing-point due to its central location in the vicinity of the Zeus temple and the direct access it provided to the Roman road to Cotyaeum (Kütahya).

[1] According to reports by European travellers, the ancient parapet remained in use as late as 1829, having been replaced today by an iron railing.

[1] Around 290 m upstream, another well-preserved, almost identical five-arched Roman bridge leads across the Penkalas.
