In a field examination carried out in the early 20th century, the four main vaults of the bridge were found in ruins, while nearly all piers and the seven minor arches had still remained intact.

[1][2] The Aesepus Bridge is located in northwestern Turkey, 8 km north of Sariköy, approximately 5.6 km upstream of where the Gönen Çayı flows into the Sea of Marmara, slightly above the point where the narrow river valley opens into the wide estuary plain and a modern bridge carries the highway 200 across the Gönen Çayı.

[6] The exposed upper part of the piers showed four parallel, slot-like hollow spaces running through the entire length of the structure, which were meant to reduce the load on the vaults.

[7] The well-preserved paving of the remaining roadway is made of large, occasionally squared stones, and rests on the roof slabs of the hollow chambers.

[4] Since the Gönen Çayı at the site passes close to the west slope of the valley, the western abutment is comparatively short.
