Work will resume near two roundabouts next week, causing traffic in and out of Cromwell to be detoured.
Cromwell drivers will be directed to detour routes previously in use until early June.
Waka Kotahi NZ Transport Agency principal project manager Brendon French said the roundabouts were opened in June as a temporary measure but parts of adjacent roads needed to close for further work to be completed.
The roundabouts are at the SH8B/SH6 intersection and the Barry Ave/SH8B intersection.
Barry Ave is funded by the developer of the Wooing Tree subdivision, and the SH8B/ SH6 intersection is government-funded through the New Zealand upgrade programme safety project, managed by Waka Kotahi.
‘‘We wanted to give people plenty of notice that the roundabout routes are closing for a few months until they can be opened permanently before Christmas,’’ Mr French said.
‘‘Most people appreciated the opportunity for an early test drive of the new roundabouts ahead of their official opening in December.
‘‘We could only do this because winter temperatures were too cold to successfully apply a permanent topcoat seal to both roundabouts. In the meantime, crews have been preparing the area for landscaping and building footpaths.’’
The detour would remain until late November and was approved for all heavy vehicles.
Work to complete the two roundabout routes included landscaping, permanent sealing of both roundabouts, roadworks linking the two and building a cycle and pedestrian underpass near the Barry Ave/SH8B intersection roundabout.
From mid-September, SH8B would be closed between Sargood Rd and the Wooing Tree roundabout for the underpass work.
