Heavy traffic on Rejtő Jenő Street and a loose manhole cover in the middle of the street

Dear Editors! Rejtő Jenő Street is a small street next to the Pest Hungarian Theater, which most drivers, apart from the residents, use to avoid having to wait at the Izabella / Wesselényi traffic lights. Cars pass by at a fairly high speed. According to former residents, there used to be a sign prohibiting passage at the beginning of the street... But currently, a bigger problem is that in front of Rejtő Jenő 2. there is a dislodged, loose manhole cover, which cars regularly drive through at high speed, and when that happens, the street is noisy. It is very annoying. Do you think there is a possibility or hope that the traffic on the street will calm down a bit? And will the noise from the manhole cover also stop?
