Roadside and Drainage
Roads and Maritime Services develop and implement policies and strategies that facilitate the strategic management of road corridor assets. Corridor assets include safety barriers, fencing, culverts and other drainage, road landscape, slopes and retaining walls, noise walls, and rest areas.
Maintenance of the roadside corridor includes maintenance of the corridor assets as well as vegetation control (mowing, landscaping, tree maintenance), snow clearing, graffiti and litter removal. The QA maintenance specifications show the target intervention levels and responses.
Roads and Maritime Services has a framework for the long-term management of culverts across Roads and Maritime Services road networks to enable road network availability and maintain road user safety. Roads and Maritime Services have developed two guidelines as tools supporting the framework (accessible using the links below).
Roads and Maritime Services “Culvert Inventory Collection Guideline” shows the information collected and stored for each culvert. Roads and Maritime “Culvert Risk Assessment Guideline” outlines how culvert risk assessments are completed.
