I have had the following feedback from the City Council :
"The closure on Riverside Drive is between 19:00 hrs and 06:00 hrs Sunday to Wednesday, Thursday and Bank Holiday Monday closure is 21:00 hrs to 06:00 hrs.
There are 13 warning signs in total in advance of the roadworks.
The diversion is clearly signed as Perth Road/Hawhill/West Marketgait and reverse. The diversion at Perth Road is at the east side of Invergowrie and not at Riverside Inn as there is a weight restriction on the bridge at this location.
We recognise that some traffic is using side streets such as Roseangle but we believe this is local traffic and I do not think any further signing will alleviate this issue.
Full discussions took place with Tayside Police and Network Management regarding suitable diversions, signing and programming of works."
