Why have some roads had no work on them for a number of years?
Roads are constructed with pavement and surfacing materials. The road pavement provides the necessary structural strength for durability, and the surfacing provides the smooth trafficable layer for good riding experience. Pavement has a longer life than the surfacing, which needs to be renewed periodically depending on the type of materials, traffic volumes and types of vehicles using the road. The typical useful life of pavement is between 40 to 70 years and surfacing between 20 to 30 years.
What can I expect?
DIT is committed to keeping impacts of construction works to a minimum and to keep the community informed of upcoming works. As works progress road users and residents may experience:
- Temporary lane closures, parking restrictions or detours
- Traffic and pedestrian management
- Increased traffic in and around local streets due to detours
- Noise and dust from construction activity
- Excavation work on roads or footpaths
DIT will ensure affected residents, businesses and road users are made aware of any works prior to commencement via the media, letter drops and/or road signs advising of upcoming works.
