"He was clear he could not promise us a four-lane highway under the government priorities. We're disappointed about that."
Twyford said it was not his place as Minister to decide on particular roading projects.
"Operational decisions about the priority and timing of projects are made at arm's length of the Government by the New Zealand Transport Agency board."
"There will be safety improvements made to State Highway 1 including more passing lanes, pull-over bays, upgraded intersections, median and side barriers, and maybe even four lanes in some places. NZTA will make the best decisions on this work," he said.
Last week the Government announced a notoriously dangerous intersection on State Highway 1 just south of Whangarei would get a roundabout and other work designed to improve road safety.
Associate Transport Minister Shane Jones announced the safety improvements to the Loop Rd intersection of SH1 and SH15.
