DP roads explained: what 12m, 18m and 30m widths mean for your project

Every road in a municipal Development Plan carries a reserved width, set by PMC or PCMC when the DP is drawn up, long before construction begins. That number, 12 metres, 18 metres, 24 metres, 30 metres, decides how much land is reserved for the road corridor: carriageway, footpaths, service lanes and utility ducting all have to fit inside it.

We've executed DP roads at 12m and 24m widths, and 18m and 30m widths, across projects including Sus Road in Pune.

Why the width changes the build, not just the size

A 12m DP road is usually a single carriageway with footpaths, built to serve a local township. An 18m or 24m road typically carries a divided carriageway with a central median, which changes drainage design, requires a different paving sequence on each half, and adds median kerb and planting work. A 30m road is often a full arterial with service roads on both sides, meaning three or more separate paving operations running in parallel rather than one.

Getting this wrong at the tender stage, treating a 30m arterial like a wider version of a 12m road, is how schedules slip. The reserved width isn't just a bigger number; it's a different construction plan.

What we bring to it

Because we run our own asphalt and RMC plants and our own paving, grading and compaction fleet, we sequence multi-carriageway DP roads as one coordinated operation rather than stitching together subcontractors for each width band.
