Árpád Bognár, CEO of construction company Swietelsky Magyarország, said the early reopening will mean cost savings for the city, as shuttle buses will then run on shorter routes.

In the ongoing renovation of the entire M3 line, the northern section between Újpest Központ and Lehel tér was completed in the spring of 2019, and the southern section between Nagyvárad tér and Kőbánya-Kispest in October, 2020.

Reconstruction of the central section, consisting of nine stations, between Lehel tér and Nagyvárad tér began in October, 2019. Of those, the Kálvin tér, Corvin-negyed and Semmelweis Klinikák stations reopened in May.
