 Due to poor financial circumstances, by 2003 just the section between Tupolevskaya and Rabochaya was completed (with no intermediate stations).At that time the plans changed and the authorities decided to connect the two banks of the Irtsh with a metro bridge, going between one station on the right bank and three on the left bank.The combined metro (lower level) and motor-vehicle (upper level) bridge was built and opened to vehicular traffic in 2005.
