Heavy traffic congestion on Halos Road Head of the Mazandaran Road Management Center: Currently, the traffic on the Mazandaran roads is established in both directions, but we are dealing with heavy traffic congestion on the Kandavan axis, the south-north axis in the Siabish area up to the Zangula bridge. The traffic on the Haraz, Svedko and Kaysar roads flows normally and smoothly and no special problems have been reported when passing through these roads.
