The NZ Transport Agency has apologised for what it called a communication breakdown which meant it didn't advise transport operators about closing SH4 last weekend.
The Road Transport Association fired a broadside at the NZTA last Thursday when it found out SH4 between Whanganui and Raetihi would be closed from 6.30am-6.30pm on Saturday, Sunday and Monday.
RTA central area manager Tom Cloke said the decision to close part of the highway just north of the Fields Track turnoff would upset the transport industry and other motorists.
"Are we wild? Yes, we are. We've had absolutely no consultation from NZTA over this decision to close the road. But the last time we met them they promised faithfully they would," Mr Cloke said.
Yesterday NZTA highway manager Ross I'Anson said the agency values its relationship with the Road Transport Association and as a rule kept them informed about road works that will have an impact on their members.
