Four-year mo­tor­way de­vel­op­ment al­most ready to roll

De­lays around Hills­bor­ough Rd occurred be­cause the ground was swampy and a sig­nif­i­cant amount of rub­bish was un­cov­ered dur­ing ex­ca­va­tion, which sur­prised work­ers, says Mr McDon­ald.

Ground con­di­tion and heavy rain in 2006 also caused de­lays.

The Auck­land Vol­canic Cones So­ci­ety worked with the agency to pro­duce the bare-rock ef­fect un­der the Do­min­ion Rd bridge af­ter find­ing solid basalt around Mt Roskill.

Christ the King School, on the cor­ner of Richardson Rd and the new mo­tor­way, was also de­mol­ished and re­built less than 50 me­tres away to avoid noise dis­rup­tion from the ex­ten­sion.

The agency has worked with Friends of Oak­ley Creek and Mr McDon­ald says around 250,000 na­tive trees and shrubs have been planted through­out the construction. He is par­tic­u­larly proud of the ca­ble-stay foot­bridges, which he says are an “en­gi­neer’s de­light”.

Mr McDon­ald says projects of this scale are al­ways sev­eral years in the mak­ing and then “all of a sud­den ev­ery­body is at the right place at the right time and it hap­pens”.

More than 2000 peo­ple were in­volved in the construction of the mo­tor­way at var­i­ous times, with about 250 peo­ple work­ing on it at any one time.

The area link­ing to Richardson Rd will open first and a rib­bon cut­ting cer­e­mony is planned.
