"Safety improvements to the southbound lane were completed late last year and now we've finished the northbound lane, we can remove the temporary barriers," Wilton says.
The improvements included moving street lights and installing roadside barriers, so it's safer and more consistent with the rest of the expressway. The temporary steel barriers provided a safe work area, protecting construction workers from live traffic while they upgraded the state highway.
"Removing the barriers is a complicated process - first the state highway must be closed, and traffic detoured for up to five nights in a row. The closure is needed as a combination of trucks, forklifts, and excavators are used to remove the barriers, while crew unpin them from the road. We need to keep our people safe and can't have them standing beside live traffic, with no protection, so the road needs to be closed," Wilton says.
