The 15 July Martyrs Bridge (Turkish: 15 Temmuz Şehitler Köprüsü), unofficially known as the Devlet Bahçeli Bridge (Devlet Bahçeli Köprüsü), located in Adana, Turkey, is a combined road-rail bridge under construction. Named after Turkish politician Devlet Bahçeli (born 1948), it crosses the Seyhan River.

The bridge will connect the districts Seyhan and Yüreğir in Adana. When completed, it will have a length of 825 m (2,707 ft) and a width of 40 m (130 ft). It is expected that the bridge will be the fourth longest in the country. It will carry three motorway lanes and one railway line in each direction. It is projected that the bridge's daily traffic will be at 55,000–60,000 vehicles. The project's cost is budgeted at ₺ 120 million (approximately US$42.5 million as of March 2016).

It is commissioned by the Metropolitan Municipality of Adana. The construction of the bridge began officially with the foundation stone-laying in a ceremony held on 30 March 2016. It is expected that the bridge will be opened in the second half of 2017.

The bridge is named after Devlet Bahçeli, current leader of the Nationalist Movement Party (MHP). He is a native of Osmaniye, which was part of Adana Province in the past.
