Hi, You've not actually closed Tarvit Street. You've placed your new road, highway=construction, on top of the existing highway. Thus making a duplicated highway while having no effect on the existing highway.

Please see here for the use of the highway=construction tag:- https://wiki.openstreetmap.org/wiki/Tag:highway=construction

If a length of the highway is closed for construction work then that piece should be sectioned off and tagged appropriately, preferably with the conditions of closure ie time scale, or reopening date. Please don't forget to return and reopen any temporarily closed highway.

If it's short closure I would not bother as it takes time for the effect to trickle down to routers and the many maps. Then again quite some time to show as open again 

Regards Bernard.
