$2m Airlie Rd bridge job set to begin
The replacement of Airlie Rd bridge gets under way this week, with disruptions to traffic to be ‘‘kept to an absolute minimum’’.
The single-lane bridge, built in 1937, has courted controversy in recent months, with its upgrade cost ballooning to $1.92 million due to increased construction prices, re-tendering and consent requirements from Kiwirail.
The new, two-lane concrete bridge will be completed before the end of July, says Porirua City Council acting general manager of asset management and operations Geoff Marshall.
‘‘During this work the existing bridge will be removed and demolished. It is possible that some of the timber from the bridge could be used in future but the bridge in its current form will not be preserved and used in the future on the current or other sites.’’
Mr Marshall says a conservation architect has been engaged to record all heritage values of the existing bridge that will be lost from its replacement.
The new bridge will be constructed in two stages, enabling the road above the railway to be open at most of the times during the planned construction period. Affected residents and public will be informed in advance of any planned road closures.
Mr Marshall says current speed and weight limits imposed on the existing bridge will be lifted once the two-lane bridge is in place.
To offset the cost, PCC will be eligible for an NZTA subsidy of $755,000.
