Bolton’s online pothole reporting isn’t shown in the available council information, but the highways pages do point to the borough’s roads and pavements service. For a pothole, the closest relevant page is roads and pavements or roads and pavements.
For street-related issues, Bolton asks you to give the street name, a precise location, and any identifying number on the lamp/sign/bollard, then the council will log the case and arrange an inspection and repair. The available records also say missing drain covers can be reported via the Bolton Council website.
