Hi, because the new Erjos-tunnel is work in progress, I asume, there will be in the future more changes in this area.. My intention is to document the date, on which the highway is taggt. I don't know a reliable tag for the checkdate. If you know a realiable tag, please feel free to change the tag. But start_date is not the right one for this. I assume the start_date (=opening the street for traffic ) was a few weeks (or month's  ? ) earlier.
