Canterbury councils want to spend about $10 billion on transport upgrades and maintenance over the next decade.
The region's mayors have agreed on a wish list, called the draft Regional Land Transport Plan, and will seek local feedback from early next year.
Among the most important projects are a second bridge over the Ashburton River, to keep traffic moving when the river is in flood, and a bypass around Woodend, north of Christchurch.
Canterbury Regional Transport Committee chair Peter Scott spoke to Corin Dann.
