Stormwater u-channels are now in place and the slope above the southern side of the road hydroseeded.

With just two weeks until the completion date of December 20, Waka Kotahi says it’s making good progress on Coromandel’s new State Highway 25a bridge.

Last week the team finished the soil nailing which stabilises the slip-face, Waka Kotahi said.

“They are now completing the grouting getting the mesh in place and bearing plates on the slip face.”

The pavement on the western road approach was finished and the kerb channel and transition side barriers between the road approach and the bridge were installed.

On the eastern approach, precast stormwater u-channels were now in place and the slope above the southern side of the road was hydroseeded.

On the bridge, the barrier stitch pours were finished and the elliptical top-rails installed. A layer of asphalt was laid on the bridge deck to level the surface.

The next steps were to chip seal and lay the final asphalt layer all the way from one approach to the other, including on the bridge deck. This would require a few days of dry weather.

“We’ll also install the side barriers on the approach roads, continue with the stormwater drainage, and working through finishing works such as line marking and installing signage.

“Every week is bringing us a step closer to completing the bridge.”

SH25 works ongoing

Waka Kotahi said repairs were continuing with traffic management in place at several sites along State Highway 25.

At Ruamahunga, work continued to stabilise the slip face, with stop/go traffic management in place and stop/stop when helicopters were in use. This work would be paused from December 22 until January 8, with the road reopened to two lanes during that time.

Repairs under way at Pumpkin Hill and Wharekaho.

Work to repair under-slips at Wharekaho and Pumpkin Hill would also pause from December 22, again with both lanes available to traffic over the holiday period.
