After years of putting the project forward, Kiama Council has received a windfall grant of $500,000 for safety fencing on the highway at Bombo.

The grant has come from the NSW Government's Road Safety Program, and has to be spent by the end of June.

At the moment, the section north of the Spring Creek crossing has no barrier to guard walkers and cyclists against 100km traffic.

"The new barrier will extend from the Spring Creek bridge to at least to the Bombo Railway parking bay, and hopefully further north," says Council's Acting General Manager, Mike Dowd.

"It all depends on the standard that Transport for NSW will specify for along a road like this.

"The concrete barriers at the northern end are for freeways, and this stretch might only require metal fencing."

He is hopeful of Transport for NSW being able to use its expertise and resources to complete the work, rather than Council.

"Doing work on a 100km road is complex as there are many permissions to obtain and many challenges to ensuring safety of workers and road users" he says.

"Transport for NSW does this work on a routine basis.”

He is hopeful that maintenance work can also be done on the footpath, which is part of the Kiama Coast Walk, at the same time the fence is being installed.
