Caibidil:
Living on the section of road between Ballinacurra/SCR junction and Lifford avenue/SCR junction, I cannot see cars being deterred by putting barriers half way across the SCR road at the Lifford avenue/SCR junction - as it is two way on both sides of this junction in SCR, cars will treat the barrier like a parked car and just manouvere around the barrier and continue on their journey.
A full block here or blocking the lane coming down off the bridge at the Ballinacurra/SCR junction would function better at reducing the number of people that use the SCR as a rat run.
Main requests:
Consider a full block at the SCR/Lifford Avenue junction.
Main reasons:
People will just manouvere around the proposed barrier as is.
