I removed the highway=construction tag as it was an erroneous use of the tag. That tag is specifically for roadways that are under construction, to be used with an accompanying construction= tag indicating the final form of the way. It is not to indicate the usage of the way, such as an access road for construction crews to access a site.
In the change set you submitted 5 minutes after posting this question you deleted the way entirely and failed to add the permanent fences you mentioned in your change notes. Inaccessibility is not a good reason to remove a feature which still physically exists. Rather it is more appropriate to separate the impassible portion of the way and add some indication of impassibility such as access=no, preferably with the attending obstruction such as the permanent fence.
