White-Topped Roads in Bangalore: A Buyer's Guide to the Concrete Upgrade
Seldom does a civic promise show up as visibly as a freshly poured grey road. Bangalore started swapping asphalt for concrete on its main roads in 2018, a method known as white-topping, and the first phase has long been finished. This guide describes the technique, the programme's position in 2026, how it affects homes beside these roads and what buyers can check on site.
Why concrete replaces asphalt
Asphalt gets soft in hot weather and breaks up wherever water lingers, which is why potholes appear after each monsoon. For white-topping the top of the old road is milled off and a cement concrete layer is cast over the base. Pale grey is the result, and it gives the method its name.
The city's road agencies design concrete to serve for between 20 and 30 years, and building it costs more than double what bitumen costs per km. Its advantage is that repairs become scarce, since potholes rarely form.
The latest work extends well past the surface and amounts to rebuilding the street itself. These are the usual extras:
- Under-footpath ducts for electrical and telecom cabling, which keep the carriageway intact afterwards
- Drains and inlets along the sides, for rainwater
- Footpaths and kerbs, laid afresh
- Street lights and lane markings, with fire hydrants on certain central roads
Phases to date
Work began under the city corporation, the Greater Bengaluru Authority now runs it, and B-SMILE, a state-owned project company, builds new stretches. By August 2026 the first phase was complete at 196 km across the city. The second phase is of about 120 km, with about half done and the balance due by the close of December 2026.
Preparations for a third phase are under way, estimated at Rs. 3,000 crore. Its quoted length has changed more than once, so it is best judged when the list of roads comes out. Earlier phases overshot their deadlines and contractors were fined in 2025 for slow progress, so any date for a stretch still being dug needs caution.
Living on the road
Several gains are immediate. Rain does not spoil the surface, cables run in ducts and repeat digging should ease. Wider, unbroken footpaths help children, older residents and people who walk to reach a bus stop or the metro.
Other effects differ by building. Because concrete goes over the old base, the road frequently ends up higher, and a gate or basement ramp that is lower than the road can let heavy rain in. Buried pipes raise another issue, since water and sewer lines left under the carriageway are hard to reach later, since repair needs a cut in the slab and a patch that seldom matches.
The works themselves are disruptive. With half of the road rebuilt at once and each section closed while it cures, residents live with diversions, a narrow road and hard entry to gates and parking for months. Shops along the stretch tend to lose customers, which matters to anyone relying on ground-floor rent.
Finished roads and a tunnel on paper
Reports tend to place concrete roads next to the Hebbal-Silk Board tunnel, although the two are far apart. White-topping has roads that are finished and contracts that are live. Bids had come in for the tunnel, but nothing was awarded by early October 2026.
A buyer can drive on the concrete road at the gate today, whereas the tunnel is only a possibility. It deserves little weight in what buyers pay for homes at present.
Questions to answer on site
Standing in the street settles most doubts. A buyer in Bangalore eyeing a white-topped stretch should ask the following:
- Is the road complete, under work or only on the list for a later phase?
- How does the road level stand against the gate, the ground floor and the basement ramp?
- Do inlets and side drains run by the kerb, and what does the street look like after heavy rain?
- According to residents, has water reached the basement since the rebuild?
- Is the footpath continuous as far as the building, with no open ducts?
- If work continues, what finish date do site engineers give, and is there room for delay?
- Does the whole peak-hour drive to work hold up, since one good road cannot fix a bad junction?
A better road lifts a single street, though a location rests on more than that. Water, drains, buses and metro, and the distance to work count for far more in a home's value. Through the contact page, the team can be asked about the current state of the roads that lead to any project.
