Is this plot in a proposed road widening line?
Proposed road widening around Chennai is mapped in three bands of final road width, 18 to 24 m, 27 to 30.5 m, and 45 m and above, and a plot inside a proposed alignment gives up that strip to the wider road. Drop a pin and the check tells you whether the point falls in an alignment and in which band, or how far the nearest one is.

Road widening, briefly
The future edge of a road the planning authority means to widen. New buildings keep their setback from this line, not from today's road edge, even before any widening work starts.
- Width bands
- 3
18 to 24 m, 27 to 30.5 m, and 45 m and above. The band is the final width of the road once widened.
- From the centre line
- 9 m to 22.5 m
The new road edge sits half the final width from the centre line: 9 to 12 m for the first band, 13.5 to 15.25 m for the second, 22.5 m for the third.

Chennai, Tiruvallur, Kancheepuram and Chengalpattu. Elsewhere the answer is Not covered, never Clear.
How to check road widening for a plot
- 1
Place the pin on the road side of the plot
Widening takes the front of a plot, so put the pin where the plot meets the road. Paste a Google Maps link or use your location while you stand there.
- 2
Press Run
The pin is tested against the proposed road widening alignments.

Read the verdict
Inside an alignment reads Flagged with its width band. Outside, the answer gives the distance to the nearest alignment. Outside the four districts it reads Not covered.
When it helps with land
A road-front plot or shop
A strip lost to widening shrinks the buildable area and the frontage that made the site worth its price.
Before drawing the plan
The architect has to take the setback from the proposed road line, so know the band before the floor plan is fixed.
Checking a seller's extent
Land inside an alignment normally has to be handed over free of cost, by gift deed, before a building permit is issued.
The alignment map is a first look. Confirm the street alignment and the width to be surrendered with CMDA, the local body or the Highways Department before you buy or design, and check the actual road width at the site.
Questions people ask
How do I check if my plot is affected by road widening?
Drop a pin where the plot meets the road and press Run. The answer says whether the point falls inside a proposed road widening alignment and in which final width band, or how far the nearest alignment is.
What are the road widening categories?
Three bands of final road width: 18 to 24 m, 27 to 30.5 m, and 45 m and above. The wider the band, the further the new road edge sits from the centre line: 9 to 12 m, 13.5 to 15.25 m and 22.5 m.
Can I build up to the current road edge?
No. The setback is taken from the proposed road line, even if the widening has not started.
Do I have to give up land for road widening?
Land inside a declared alignment normally has to be surrendered free of cost, usually by a registered gift deed, before a building permit is issued. Confirm the extent with the planning authority first.
Which areas does it cover?
Chennai, Tiruvallur, Kancheepuram and Chengalpattu, where the proposed alignments for the Chennai metropolitan area are mapped. Outside them the check says Not covered rather than Clear.
Is a clear result a guarantee no widening will happen?
No. It means no proposed alignment is mapped at that point. Road schemes are added and changed by the planning authority and the Highways Department, so ask them before you buy a road-front plot.
What does it cost?
1 credit per pin, charged only when the layer gives a real answer. A Not covered answer is not charged. The free road widening check page stays available; this check adds the survey parcel, a sweep of the severe layers and a saved answer.
