Innovative design in bridge
MOTORISTS will be safer on the roads thanks to the construction of a new bridge at Snake Creek, on an accident-prone section of Kyogle Road.
The bridge will feature an innovative design and numerous environmental benefits.
Located near Mount Burrell, it will employ a revolutionary construction technique never used before in the Tweed region.
Council's senior construction engineer Nigel Dobson said the new design would reduce maintenance.
“Maintenance costs will be reduced by eliminating the need for tensioning metal rods, which hold beams together on conventional bridges but are subject to corrosion,” Mr Dobson said.
“This new bridge has also eliminated the need for a central pier.
“That brings environmental benefits of improved stream flows and fish passage.”
The bridge construction will use the same pre-stressed concrete beams seen in conventional design, but for the first time will space them apart and combine them with a poured concrete deck.
A Tweed Shire Council construction crew last week poured the deck for the bridge, which will replace the old timber bridge. It is being constructed as part of realignment and widening of the section of Kyogle Road.
The work is scheduled to be completed in March, provided the construction is not delayed by further wet weather and heavy rainfall and is expected to cost $1.4 million.
The section of road has a history of motor vehicle accidents.
