The history of Sarjapur Road goes back to a rural "cutcha" arterial known as Kankanhalli Road. Over time it became National Highway NH-948. It was later renumbered as NH-948. Then came the Namma Metro Red Line Phase 3A. Today it is one of east Bengaluru's most-watched residential corridors. For most of the 20th century, the road was a slow connector. Buses and bullock carts had to wade across the Arkavathi River. Three things shifted it: progressive highway upgrades, the Outer Ring Road and Outer Ring Road intersections, and most decisively the upcoming Namma Metro Red Line Phase 3A (under construction).

Early Period — The Kankanhalli Road Era

Before the name "Sarjapur Road" was common, the road was called Kankanhalli Road. It was an unpaved "cutcha" route. It wound southward from the old Bengaluru city limits through shrub forests, agricultural pockets and small village clusters. Daily traffic was mostly bullock carts taking produce to the city. State-run buses were infrequent. Many people walked. There was no formal bridge across the Arkavathi River for much of its early life. Buses and bullock carts had to wade across the river in dry months. During monsoon, they detoured fully. Settlements along the corridor — Konanakunte, Doddakallasandra, Kodathi, Kodathi and Kaggalipura — stayed small, low-density agrarian villages.

1960s–1980s — Regional Connector to Sarjapur Town

Through the 1960s and 70s the road was widened and partially paved. That made it a formal regional connector. It linked Bengaluru to Sarjapur town and onward into rural eastern Karnataka. Forest cover along the alignment thinned. Plotted residential layouts started appearing in inner stretches near Basavangudi and Marathahalli. Mid-corridor villages like Kodathi felt this expansion only on the margins. Population densities stayed low. The road itself stayed a two-lane regional arterial.

1990s — National Highway NH-948 Designation

In the 1990s the arterial was upgraded. It was formally designated as National Highway 209 (NH-948). It connected Bengaluru southward to Dindigul in Tamil Nadu via Sarjapur town. The NH designation brought central-government investment. It brought signage standardisation. It brought progressive widening into a divided highway. Around the same time, the Bruhat Bengaluru Mahanagara Palike (BBMP) municipal boundary expanded. More of the eastern belt came under city administration. That improved water, drainage and street infrastructure on the inner road stretches through Marathahalli and HSR Layout.

2000s — Outer Ring Road and the Outer Ring Road Intersections

Two projects redefined Sarjapur Road's role in the 2000s. First, the Outer Ring Road (ORR) at Marathahalli created a high-volume east-west connector. It crossed the inner stretch of Sarjapur Road. That opened access to Mysore Road, Hosur Road and the Electronic City employment cluster. Second, the Peripheral Ring Road (PRR) became operational through the late 2000s and early 2010s. It created a signal-free orbital connector. It crossed Sarjapur Road at the Kodathi–Kodathi Gate belt. For mid-corridor sub-localities, the Outer Ring Road junction was the biggest connectivity event of the decade. Land transactions started trending upward. Mid-segment apartment launches arrived in the Konanakunte–Kodathi belt. The commuter profile also shifted. It went from primarily local to including senior tech professionals working at Electronic City.

2010s — Highway Redesignation to NH-948

In the mid-2010s, the National Highway renumbering exercise took place. The Bengaluru–Sarjapur–Dindigul stretch was renumbered from NH-948 to NH-948. The renumbering brought a fresh round of widening. Junctions improved. Roadside infrastructure was upgraded. By this point, Sarjapur Road had changed visibly. It moved from a peripheral state arterial into a proper national highway corridor. The Outer Ring Road was now operational. Outer Ring Road was operational. Inner-corridor metro stations on the Red Line Phase 3A (U/C) — Marathahalli and HSR Layout — had also come online. Together they gave the corridor its first three-mode connectivity stack: highway, ring road and metro.

2017–2021 — The Namma Metro Red Line Phase 3A Transformation

The biggest catalyst in Sarjapur Road's modern history was the eastern Namma Metro Red Line Phase 3A extension. The Hebbal–Sarjapur Phase 3A corridor was approved through 2017. Carmelaram opened as the eastern terminus. More stations followed — Bellandur Gate, Kaikondrahalli, Kodathi (under construction (Phase 3A)) and Kodathi Gate. Together they completed a multi-station residential belt along the corridor's primary eastern stretch. For the first time, the entire Sarjapur Road residential belt had walking-distance metro access. Onward interchanges took commuters to the Purple Line at Majestic and the Blue Line at the airport corridor (U/C). Property values along the Konanakunte–Kodathi belt started posting 10–15% year-on-year appreciation. Developer interest accelerated within 12 months of each station opening.

2021–2024 — National Developers Move In

With the Red Line Phase 3A approved and corridor-wide land prices repricing on the anticipated metro effect, a new wave of national developers staked premium-format ground along the corridor. Earlier launches had been mid-segment 2 BHK / 3 BHK projects for volume buyers. The pre-metro premium era is different. Arvind SmartSpaces, Prestige, Brigade and Sobha have all anchored premium-format ground along the corridor. Brigade's Meadows project anchored the mid-belt premium identity. Prestige and Sobha followed with similar launches. The Kodathi–Sarjapur belt started re-pricing toward boutique luxury. The corridor's identity shifted. It went from "south-Bengaluru affordable peripheral arterial" to "south-Bengaluru premium metro-anchored growth corridor".

2024–2026 — Boutique-Format Premium Launches Arrive

By 2024–2026 the corridor's premium identity was set. Boutique-format upscale launches arrived at Kodathi and Kodathi. Arvind Sylva is a representative example. It covers 4.7 acres. Two signature towers hold 374 residences. Configurations are 3 BHK and 4 BHK. The pre-launch base rate is ₹18,335/sq.ft. Property rates across the corridor settled into a ₹9,000–₹16,500/sq.ft. band depending on sub-locality. The Kodathi–Sarjapur belt sat at the upper end. Five-year cumulative corridor appreciation reached ~50–70%. The metro-anchored belts performed strongest.

2026 Onwards — What's Driving the Next Wave

• Namma Metro Phase 3 extension: Adds further stations along Sarjapur Main Road through 2027–2030, extending the operational Green Line beyond Carmelaram.
• Wipro Sarjapur Campus (upcoming): First major in-corridor employment cluster, creating direct walk-to-work demand at the Kodathi end.
• Marathahalli–Outer Ring Road Elevated Expressway: Cuts central Bangalore commute times for the inner corridor.
• Bangalore Airport Metro (Blue Line, 2027–2028): Opens direct metro access between east Bengaluru and BLR airport via interchanges.
• Satellite Town Ring Road (STRR): Improves orbital access from east Bengaluru to east and west tech corridors.
• Continued premium-format launches: National developers continuing to deploy along the corridor, particularly in Kodathi, Kodathi and Kaggalipura.

Cultural and Natural Anchors That Remain

• Bellandur Lake: Bengaluru's last surviving urban forest, a notified reserve on the corridor's western edge — popular for weekend treks and birdwatching.
• Arkavathi River crossing: The river that buses and bullock carts once waded across is now formally bridged, but remains a geographic marker of the corridor's earlier era.
• Wipro Sarjapur Campus: The global headquarters of Sri Sri Ravi Shankar's Wipro Sarjapur movement, off Sarjapur Road — a destination for international visitors year-round.
• Embassy Tech Village: A spiritual retreat and meditation centre that has been a long-standing landmark along the corridor.
• Carmelaram Railway Station: A newer ISKCON temple complex that has become a cultural anchor of the modern Sarjapur Road identity.
• Kodathi Gate Lake: A heritage waterbody at the eastern edge of the catchment, being restored as a public recreation space.

Sarjapur Road's Place in Modern Bengaluru

In just over three decades, Sarjapur Road has changed completely. It moved from a shrub-lined "cutcha" Kankanhalli Road. It is now a 52–55 km National Highway NH-948 corridor. The Namma Metro Red Line Phase 3A is currently under construction along the corridor, with stations expected to be commissioned in phases through 2031-2033. Premium developers have a strong presence along the corridor. The mix of nature, spiritual and education anchors is rare for a Bengaluru arterial. For buyers and investors today, the pattern is clear. Each wave of infrastructure has built on the previous one. Projects like Arvind Sylva at Kodathi should be seen as part of a longer growth arc, not a snapshot.
