Ekrem İmamoğlu, Istanbul Mayor, announced on his official social media account the start of "testing" (test drives) of the important Ümraniye-Ataşehir-Göztepe metro line for the city. As you know, this is a transport long-term construction. The line was suspended in 2017, and it began to be implemented.
By the way, thanks to the development of transport infrastructure, housing in Ümraniye has become more expensive, although the main impetus for this was the Marmaray project.
The media reported on the opening of the next line of the Istanbul metro in the Asian part of the metropolis last week.
