The Otago Regional Council says Fulton Hogan has to "do better" after debris left on the road left a woman stranded in her wheelchair in the middle of an intersection.
Fulton Hogan is working on Great King St to create the regional council's new bus hub.
Business owner Liane Craig has co-run her St Andrew St business, Pop-In Emporium, for three weeks.
She said after the contractors finished work on the St AndrewSt-Great King St intersection, they left the road littered with rocks.
Earlier this week she ventured on to the intersection for the first time in three weeks, she said.
