Video evidence of one van driver ignoring the no-entry was this week posted on Twitter by Deputy Montfort Tadier. However, he has since removed the footage.
In response to the post, St Helier honorary police said: ‘Officers patrol this area when available and are proactive in all areas of concern which parishioners have requested patrols around. Any offenders are reported to the parish hall.’
Deputy Tadier replied: ‘A camera would solve the issue. Then again, [States] police HQ is right next door too…’
The road was initially closed to southbound vehicles last year during an extended period of roadworks.
At the time, Deputy Russell Labey said that ‘almost by accident’ the measure had solved traffic problems in the area.
Over the following months, he lodged a proposition to make the one-way system permanent and States Members voted in favour of it by 28 votes to 19.
Cars using the Clos des Pas Shopping Parade, at the bottom of Green Street, are still allowed to exit the retail area and head southbound, where the road is formed of two lanes. LibertyBus vehicles, cyclists and emergency vehicles are all exempt from the rules.
One Green Street resident, Josh Eyre (36), said he had witnessed a number of road-rage events since the introduction of the one-way system.
‘Those going north are determined not to stop for traffic coming the other way and they know they should not be going down there. I have seen lots of gesticulations, Mexican stand-offs and people refusing to budge,’ he said.
‘It has only been shouting and gestures so far but if you had the wrong combination of people going down that road then I think it could be worse.’
Mr Eyre, a finance worker, added that he supported making the road one-way southbound but thought the road’s current format did not work.
‘They have tried to make the road safer for pedestrians but by keeping buses going southbound down there, they have to go on the pavement when they meet a car coming the other way,’ he said.
‘When it was closed southbound, that was used as a test-case for making the closure permanent but in that scenario buses did not have access southbound down either.’
St Helier honorary police and Deputy Labey were contacted for comment but were unavailable.
