We’ve received some comments about the thickness of the concrete going down along Durham Street. The road is 200mm thick across the full width. However, the view one gets from looking at the concrete road seems much deeper. This deeper concrete thickness is called the thickening.
As the most loaded area of the road, from things like heavy trucks and buses, the thickening is required along the edge to strengthen these parts of the slab.
This thickening is 600mm deep and 600mm wide, and runs along the edge of the road. The photos below show the difference in thickness through the pavement (photo 1) and the edge as it appears from the outside (photo 2).

Spring Street and Durham Street Intersections
The opening of the Spring Street section between Willow Street and Durham Street to one way traffic has been delayed until the end of this week. We need to seal the concrete joints which requires cooperation from the weather. This should happen this week. Vehicles will be able to travel from Willow Street to Cameron Road and turn left only at Durham Street. There will be continued construction activity so please drive carefully.
Preparation work for cobbles will continue.
Outside Carpark building:
- Another two concrete pours happened last week, one on the footpath and one on the roadway.
- Construction of the footpath and roadway across lane one of the parking building will happen this week. This means there will be one entry lane and one exit lane starting today (8 July).
Outside Trustpower and Beaurepaires:
- The rain garden and garden pits have been excavated. The new rain garden will be placed this week.
- Foundations will be placed for rain garden pits.
- A new cesspit and connection will be installed outside Beaurepaires.
From Beaurepaires to Elizabeth Street:
- An environmental filter manhole has been placed and connected. There are several of these manholes throughout the project where the stormwater is filtered before travelling through to the harbour.
- The footpath and roadway outside Aspire will be excavated and prepared for kerb and channelling.
- Work will start on installing an environmental filter manhole outside Palazzo Kitchens.
West side from Gengys to Elizabeth Street:
- Cement treated base metal will be laid under the new west side roadway.
- Asphalt surfacing will then be laid over this base towards the end of this week.
- The last of the kerb and channel will be laid outside the Rock Shop in preparation for cobblestone paving.
- Cobbles between the concrete footpath and the Rock Shop property boundary will continue to be laid.
Work has continued on the pavement and shaping of the lane between the University of Waikato and Spring Street.
The surface should be membrane chip sealed this week.
