Motorists driving over the Tukituki Bridge on State Highway 2 just north of Waipukurau will not see engineering contractors at work but they are being asked to stick to restrictions which have been put in place to allow the work to be carried out safely.

Speed restrictions are also in place where major work is being done at the Pakowhai and Links Rds intersection with the expressway.
