The initial stage of the $1 billion Belfast to Pegasus motorway and Woodend Bypass project has commenced, with trucks beginning to fill former quarry lakes near Kaiapoi to establish foundational embankments for the new roadway. The New Zealand Transport Agency (NZTA) confirmed that preparatory work at the Pineacres site, located north of Christchurch, has been completed, allowing gravel placement in two quarry lakes up to eight meters deep.

This project involves constructing a four-lane motorway extension, including a 7-kilometer bypass designed to alleviate heavy traffic congestion along State Highway 1 through Woodend. Recent site preparations have included setting up offices, fencing, sprinklers, truck wash facilities, and an internal haul road. Tree removal was also conducted to facilitate access to the quarry lakes.

The embankment filling is expected to continue until the end of the year, with peak activity involving approximately 13 truck movements per hour. To minimize disruption, construction hours are limited to daytime, and dust control measures such as water carts and sprinklers are in place. Temporary traffic management measures, including reduced speed limits, have been introduced around the site.

Completion of the embankment is anticipated by December, allowing sufficient time for material settlement before full motorway construction proceeds. Concurrently, seismic strengthening work is underway on the Kaiapoi River Bridge along SH1. A crew of up to 40 specialists is reinforcing 30 columns supporting the bridge piers, part of an earthquake resilience upgrade.

The seismic work includes concrete repairs, wrapping columns in carbon fibre reinforced polymer, and applying anti-graffiti and UV-resistant paint. Additional reinforcement on the bridge beams involves installing steel bars and adding new concrete supports to reduce movement during a major seismic event. Vibration monitors are also being installed to evaluate the need for temporary speed limits during construction phases.

While early ground preparation and bridge upgrades are progressing, funding for the main construction stage has not yet been finalized. The NZTA has suggested introducing tolls on the new motorway as a potential means to help finance the project.
