A major Hamilton intersection already choked at morning and afternoon peaks is about to get worse.
Drivers who use the River Road-Wairere Drive intersection are being strongly urged to avoid the junction from Monday with three days of road closures scheduled.
Construction contractor Downer is closing adjacent sections of River Road to complete vital road surfacing work.
Hamilton City Council city development manager Andrew Parsons says with work on pedestrian underpasses and footpaths nearly completed, the construction focus shifts to the road itself.
"Because of the constrained nature of the site and the vast amount of work going in, we have no choice but to close River Road at various times, in both directions, over three days," Mr Parsons says.
"We realise this will inconvenience motorists, and we apologise for that, but it's an essential part of this work and we need to get it done."
Weather permitting, closures will be on November 12 for River Rd north, from the intersection to Flagstaff shops; November 13, no turns from Wairere Dr onto River Rd, and no right turns from River Rd onto Wairere Dr; and November 14, River Rd south closed from the intersection to Harrowfield Dr.
A series of staggered closures will be in effect from 7am to 9pm, at the latest. Traffic will still be able to travel on Wairere Dr during the closures.
The intersection upgrade is still on track for completion before Christmas.
Other work in the area over the coming weeks includes final sealing of Wairere Dr from the Pukete Rd intersection to the Pukete Bridge, and installation of the new traffic signals at the Wairere Dr-River Rd intersection.
Mr Parsons urged commuters to use alternative routes, carpool, stagger journey times and work from home if they could while the work continued.
