STOP PRESS: Residents will be aware that the poor weather last weekend led to the postponement of this work. We have now been informed that it will take place this coming Sunday (11 October).
We have been informed by Cardiff Council's Network Management team that there will be a road closure on Heol Isaf (sic) at its junction with Heol Syr Lewis this Sunday (4 October) from 9am until approximately 6pm.
This will be to facilitate the planning and resurfacing of the new raised table crossing being constructed. The footways will remain open during this work for pedestrians and cyclists (dismounted).
The following maps show the extent of the closure. It is marked in red, which is quite hard to distinguish from the diversionary route, marked in purple.
It seems, however, that it is part of Ty Nant Road that will be closed from its junction with Ffordd Treforgan (according to the map - although Cardiff Council told us it was from Heol Syr Lewis) to its junction with Springfield Gardens. The recommended diversion will take you a long way around - past Danescourt, via the old BBC site, through Llandaf North and Whitchurch, around the Coryton roundabout, through Tongwynlais, up to the turn-off for Radyr.
So you may want to avoid that journey on Sunday!
Higher resolution copies of the maps can be seen here and here.
