LIVERMORE — All roads, except Routes 4 and 108, will be posted Thursday morning to keep heavy vehicles off them if it’s above 32 degrees and there’s water running from road cracks, road Foreman Roger Ferland told selectpersons Tuesday night.

Vehicles weighing more than 23,000 pounds will not be allowed on the roads because of possible damage to them. Ferland estimated the posting will last until May 15.

“They could come down sooner, depending on weather conditions,” he said.
