Roman Bridge (Ayvalı Kemer)
Ayvalı Kemer Bridge extends in the northeast and southwest direction on the Koducak Stream, approximately 1400 m southwest of the ancient city of Sillyon. The bridge, which was severely damaged due to the elements through the history, has survived only as a few blocks on the upstream spandrel wall covering the areas between the arches and the arches whose voussoirs had moved out of place. The bridge was restored by the General Directorate of Carriage Roads in 2016-2017, in line with the extant remains and data obtained.
Roman Bridge(Ayvalı Kemer Bridge)
Built with travertine blocks, the bridge has a length of 41 m and a width of 4.65 m. The deck of the bridge reaches its highest point on top of the larger round arch in the middle of the three. From the remains on the floor of the southwestern arch span, it is understood that the foundation was built with cut stone blocks. The piers of the bridge were built with rectagonal blocks that were placed on top of each other without using any mortar, and sit directly on the foundation without creating any planes or platforms. The semi-circular arches rising on the piers were built with the voussoirs placed on top of each other. Although the spandrel wall has survived in a highly damaged condition, it provided sufficient data to understand its architectural layout. While blocks of the same height were used on the facade walls of the bridge up to the beginning levels of the arches, after this level, pseudo-isodomos masonry technique was applied using one row of high and one row of lower blocks alternately. The absence of cornice blocks with different profiles or mouldings that may have been used on the upper end of the spandrel wall indicates that the parapet blocks were placed directly on the spandrel wall. Due to its architectural features, Ayvalı Kemer Bridge must have been built in the second century AD at the latest.
