Construction update on Peka Peka to Otaki Expressway North Zone (north of the Otaki River to Taylors Road)

4 MinutesBy NZ Trucking magazineNovember 2, 2018

Works are picking up between Taylors Road and Otaki Township as the NZ Transport Agency continues setting up work sites and creating access tracks for the new Waitohu River Bridge (Bridge 1).

Construction continues on Bridges 2 and 3 (northwest of the Mill Road roundabout). This month NZTA will be finishing utilities and drainage works over those two bridges. They will also be pouring concrete on the bridge decks, followed by installing barriers, bridge graphics and completing tie-ins to SH1 and County Road.

Retaining walls on the eastern and western sides of SH1 north of the Mill Road roundabout are underway. These will support the new section of local road.

The western footpath on SH1 in this area remains closed with pedestrians diverted via County Road. Pedestrians are advised to continue to use the temporary footpath and the signalised pedestrian crossing just north of the Mill Road roundabout.

NZTA has finished the western abutment of Bridge 4 (the bridge that will take Rahui Road over the realigned rail track expressway and shared path). Works on the eastern abutment will start after the rail track is moved, currently planned for Easter 2019.

Otaki Railway Station platform extension works continue, with the southern end finished and work begun on the northern section.

NZTA says things are busy out there, and advise motorists to please slow down around all works and allow a little extra time for your journey.

South Zone (south of the Otaki River to Peka Peka)

NZTA has finished all the piles on the southern side of the new Otaki River Bridge (Bridge 5) and is now working on the northern bank and abutment. Beam installation and deck construction continue on the south end of the bridge and access to the south bank remains restricted around the works.

The Chrystalls Bend public river walkway on the north bank is diverting people around the work site. The diversion is well signposted and fenced for pedestrian safety and will remain in place until around June 2019.

Works on Bridge 6, that will carry Otaki Gorge Road over the rail track, continue with a new site access formed off SH1 just south of the current Otaki River Bridge. Pavement works continue on the new sections of Old Hautere Road and Otaki Gorge Road.

This month NZTA will begin preloading works at Mary Crest and south of Te Hapua Road. Preloading involves applying many layers of material on top of the existing ground surface to squeeze the water out of the peat below. Once the required level of settlement is reached the top layers of preload material are removed and the road pavement is applied.
