Tohma Bridge (Turkish: Tohma Köprüsü), also known as Martyr Gaffar Güneş Bridge (Şehit Gaffar Güneş Köprüsü), is a road bridge in Malatya Province, eastern Turkey.

The bridge crosses the Karakaya Dam reservoir on the State road D.875 between the provinces Malatya and Sivas.[1] It is to connect Eastern Anatolia and Southeastern Anatolia regions with Black Sea Region via Malatya.[2]

Started in 2018, it was designed as a box girder bridge and built with prestressed concrete using incremental launch method by PYES Co. under the contractor Ziver İnşaat Co.[2][3] For the construction of the bridge were 12,000 m3 (420,000 cu ft) concrete, 2,700 tons steel for girders of 3 m × 16 m (9.8 ft × 52.5 ft) dimension and 4,360 m (14,300 ft) bored pile used. It features seismic base isolators on both ends to withstand earthquakes.[2] Opened on 6 February 2021, the bridge is 517.5 m (1,698 ft) long, 16.5 m (54 ft) wide and 21 m (69 ft) high with a total of 15 spans of 34.5 m (113 ft).[1][2][3] It carries two lanes in each direction.[1]
