metro (cancelled - for now)
In October 2000, Mass Transit magazine reported that the long awaited Bogota metro project has been cancelled in favour of expressway expansion. Later a busway was built and has been very successful. But it's still not a metro.
In May 2013, a tender was signed to build a 26.5 km, mostly underground metro in Bogota. The line is expected to open in early 2015.
