The construction of two additional lanes on Wairere Drive is speeding ahead, with several key pieces of work being undertaken in the next two weeks.
Work on the section between River Rd and Resolution Drive started on Monday and is expected to finish later this month.
Contractors will install the foundations for two new piers to support a sewer overbridge that will stretch across Wairere Drive; start construction of retaining walls on the southern and northern sides of the arterial, and complete stormwater trenches.
Motorists can expect disruption, as the east-bound lane of Wairere Drive where the work is being done will be closed until January 24.
Tahl Lawrence, project development manager at Hamilton City Council, said the inconvenience would be minor and east-bound motorists would be diverted along Discovery Drive.
"There's always some disruption but we're trying to do it as smartly as we can," he said.
With the help of a crane, contractors started installing the two foundations for the sewer overflow bridge yesterday afternoon.
The crane will also be used to drive 70 steel piles - which are each 12 metres long - into the ground for the retaining wall on the northern side of Wairere Drive.
Mr Lawrence said a big challenge for contractors would be the ground conditions in the area.
"Being in a gully, it's very wet. There's a lot of ground water underneath the surface."
He said contractors would maximise existing drainage and use pumps to drain out the water below the surface.
The 550-metre section is regarded as an integral part of the $84 million Hamilton Ring Road network and, once complete, is expected to improve traffic flows in the city's northeast.
Surrounding residents should receive a letter from Downer Construction with an overview of the scheduled work and the expected duration.
