The measures, which are subject to approval, are due to take effect from midnight on Tuesday and will remain in place until the end of July.

And the M7 around Portlaoise from junction 16 to 18.
Here's the scene on the M7 at Junction 17 with the Stradbally Church Choir supporting the demonstrators:

Aontú leader and Meath West TD Peadar Tóibín thinks the government's has made a serious mistake by refusing to speak to the people actually engaged in the protests:
