The road "under construction" is closed because of a compromised column base (see the photos at https://dariknews.bg/regioni/sofiia/vizhte-porazheniiata-po-nadleza-kym-boiana-koito-nalozhiha-spirane-na-dvizhenieto-snimki-2384439). Allegedly the temporary supports will be done in a week and everything should be open (until they find a way to properly fix it of course).

Officially, that segment is still oneway. Only traffic from/to the complex uses this segment. That traffic is practically negligible and drivers likely ignore the signs but they wait for each other since there is only one lane and they can't pass each other.
