History

After bifurcation, a flyover was proposed by the government of Andhra Pradesh to control traffic flow between the new state capital Amaravati and the de facto capital Hyderabad on the existing 15-20 foot highway around Durga temple. The construction of the Kanakadurga Flyover was started by Soma Company of Hyderabad on 22 November 2015 and the road level bridge was completed by 2016 for Krishna Pushkaralu. The flyover was very difficult to construct due to its plan and on the River Krishna. The land acquisition for this project cost around 100 crores for the shifting of utilities like drinking water pipelines along the road. The construction deadline was extended repeatedly between 2017 and 2020, and construction was finally completed by 30 August 2020.

It is estimated to have cost 282.4 crores, which was later adjusted to 440 crores for inflation. It has a unique and complex design with a six-lane corridor supported by a single pillar. There are two underpasses in the flyover master plan. Vertical gardening has been done on the column of this flyover along with a park for F1H2o to celebrate the 2018 F1H2o World Championship in Amaravati. The district administration has decided to allow traffic through the flyover prior to its completion to prevent traffic bottlenecks and congestion.
