N17 Pipelaying in Claregalway - Traffic Woes

Ok first thread up here and like most it's a rant... Apologies in advance
Firstly I understand Pipe Laying and road works are all perfectly necessary in Ireland as our infrastructure needs to be upgraded to cope with demand but the situation with the pipe laying in Claregalway has got to be the biggest joke in the country.
Firstly to take the N17 on during the day is no easy feat but to continue at rush hour times - no other country in the world does this - and neither do we!! So if you think that the pipelaying in Claregalwya is stopping you from getting to work on time - think again.
According to the CC themselves via the Tuam Herald
"... some of the pipe laying is set to commence this Monday from 9.30 am to 3.30 pm each day and this will cause some traffic delays over the next three months..."
Hear that - it finishes at 3.30pm. Why then am I hearing quotes of up to two hours from town to Claregalway?
Why on Monday did I myself experience a 1 hour drive from Whiriskey's to the Traffic Lights?
Finally it dawned on me what was causing the issue....
It's NOT the pipe laying that is causing the problem. It's those lovely thousand of euros worth of traffic lights and their ingenious automatic cycles that have been tweaked and fine tuned.
Having lived in Claregalway for a number of years I know this cycle off by heart. The amount of time I spent at these lights observing, knowing to slow down, when to speed up... I understand how it works, how it changes from day time to night time to ease traffic flows but I'd wonder if they consulted the council on their Pipe Laying plans and how it affects the light cycle.
On a normal day people drive from Tuam to Galway and the lights remain green for 3-4 minutes sometimes less if there is a gap in the traffic they will change quicker, they change then for the Oranmore side and allow a few cars through at a time, the time gets longer as the queue of cars builds on any side leading to general happiness in Claregalway.
So it's Green Tuam- Galway, Green Oranmore - Tuam depending on the flow of the cars.
However, if a car comes up beside Hughes Shop to the lights to turn left or right the cycle changes which, on a normal day is a non- issue as it is rare cars come up that country laneway.
The cycle changes as such for the laneway:
Green Tuam - Galway, Green Oranmore - Claregalway, Green - Hughes Out, Green Oranmore - Claregalway, Green Tuam - Galway.
So seeing as people are using the old ratruns again because they think the pipelaying is affecting the traffic the sequence is messed up causing huge delays on N17.
The pipelaying seems to be over early enough not to affect traffic in the village itself. This evening any traffic that passed the lights to Tuam direction from 4pm onwards was never stopped and moved along the road towards the roadworks like any other day.
The thing that is stopping the traffic on the Galway - Claregalway Road is the hoards of cars that may be saving a few minutes by speeding dangerously down a back road and messing up the sequence of the lights for everyone else.
Maybe I am alone in my rant or has this behaviour/setup annoyed anyone else??
