About roads.gg

Official Closures

We automatically pull data from the States of Guernsey's official roadworks system. Official closures are shown as coloured lines on the road indicating the type of disruption. Click the legend button on the map to see what each line colour means.

User Reports

Anyone can report a road closure they encounter. User reports are shown as coloured dot markers on the map, with the colour indicating the type of incident. User reports are especially valuable for unexpected incidents like accidents, fallen trees, or flooding that aren't in the official system.

Community Voting

Users can vote on reported closures to help verify their accuracy:

• Confirm - The closure is real and still active
• Dispute - The report appears to be incorrect
• Resolved - The road has reopened

Feedback on Official Data

Official closure data comes from the States of Guernsey, but sometimes it may not reflect real-world conditions. You can provide feedback on official closures too:

• Confirm - The official closure information is accurate
• Dispute - Report an issue with the official data (road is actually open, wrong dates, wrong location, etc.)
• Resolved - The road has reopened ahead of schedule

When multiple users dispute an official closure, administrators are automatically notified to review and update the information.

Discussion

Each closure has a discussion section where logged-in users can share additional information, ask questions, or provide updates. This helps the community stay informed about changing conditions.

Bus Route Information

Official closures automatically display which bus routes are affected, helping commuters plan alternative travel arrangements. When 5 or more routes are impacted, a warning is shown to highlight significant disruption.

Overlapping Works

When multiple roadworks affect the same road segment, clicking on the road will show all overlapping closures with an intuitive carousel interface. Active works are shown first, followed by upcoming and finished works, all sorted by start date.

Navigate between overlapping closures using:

• Arrow buttons in the closure popup
• Dot indicators below the closure details (click any dot to jump directly)
• Keyboard arrows (left/right) when the popup is open

This helps you see all work happening on a road at once, so you can plan around multiple closures, diversions, or restrictions in the same area.

Time-Aware Display

roads.gg automatically tracks when closures are active based on their start and end times, showing you which closures are affecting roads right now.

• Active closures - shown with full color and opacity (affecting roads now)
• Finished closures - shown with gray color and reduced opacity (past their end time)
• Upcoming works - shown with dashed lines using their type-specific colors (not yet started)

Each closure popup displays its current status ("Active Now", "Finished", or "Not Yet Active") with timing information like "Ended 2 hours ago" or "Starts in 3 hours". You can filter finished/upcoming closures using the map filters if you want to see only currently active closures.

Official closures marked as "Finished" by the States of Guernsey are completely removed from the map as they represent fully completed roadworks with no residual effects.

Official Road Line Types

Time Status Indicators

Closures are visually distinguished based on their current time status:

Upcoming works are shown with dashed lines using their type-specific colors: red for closures, yellow for diversions, blue for one-way, green for traffic management, and gray for other. You can toggle finished/upcoming closures in the map filters to focus on currently active closures only.

User Report Markers
