Speed hump modification update
The Gore District Council has had to delay modification work to a speed hump at the Ontario Street bridge.
The speed hump nearest the bridge was scheduled to be lowered and widened on Wednesday night (2 November). However, the work will now happen next Thursday night (10 November).
Transport Manager Peter Standring said the delay was disappointing.
“Unfortunately we’ve been let down by our contractor. However, we are making sure it’s rescheduled for as soon as possible.”
Mr Standring said the work would still be done at night to minimise disruption to traffic.
The bridge would be closed next Thursday from 6.30pm until 7.00am.
Mr Standring thanked motorists for their patience.
“We appreciate the size of the speed hump nearest the bridge was causing concern for some motorists and believe the modifications will make it easier to negotiate while still achieving the desired effect.”
The speed humps were installed last month to protect the integrity of the 76-year-old bridge by slowing heavy traffic. Trucks exceeding the bridge’s 10kph speed restriction have been the main cause of damage to the bridge’s deck in the past.
Motorists using the Ontario Street bridge may experience some delays over the next couple of days as work on modifying one of the recently installed speed humps is carried out.
The speed humps were put in to protect the integrity of the 76-year-old bridge by slowing heavy traffic. Trucks exceeding the bridge’s 10kph speed restriction have been the main cause of damage in the past.
Gore District Council Transport Manager Peter Standring said the new speed humps have successfully slowed down traffic. However, the Council was aware the one closest to the bridge has been causing issues.
“Given the feedback we have received, we believe we can modify this speed hump without losing its impact to slow down traffic and protect the bridge.”
Modification work starts tomorrow (Tuesday 1 November) although the bridge will be kept open. On Wednesday night it will be closed from 6.30pm to about 5.00am. There will be a detour via MacGibbon Road.
“The traffic flow on this bridge is quite high so we have scheduled the work for the night to minimise disruption to motorists.”
The modifications involve the speed hump closest to the bridge being widened and lowered.
“This will make it easier for traffic to negotiate, particularly vehicles lower to the ground than the norm,” Mr Standring said.
The Ontario Street bridge is just one of a number of old bridges in the Gore District that need to be carefully managed to ensure a sustainable roading network.
“We regularly inspect our bridge network to identify any issues before they become a risk to users.”
Enforcing speed and weight restrictions is one of the Council’s management tools. In the case of the Ontario Street bridge these restrictions have not been enough to stop vehicles hitting it at speed, causing the decking to move.
It was important for heavy traffic to observe the speed and weight restrictions on older bridges, Mr Standring said.
“We need to remember these bridges were built at the time when the maximum weight for heavy traffic was a lot less than it is today.”
