Chennai Peripheral Ring Road
NHAI

Overview
The Chennai Peripheral Ring Road (CPRR) is a 132.87-km, six-lane access-controlled expressway connecting Ennore Port to Poonjeri near Mamallapuram across five sections. Developed by TNRDC under the Tamil Nadu Highways Department, the total project cost is Rs 12,301 crore funded by JICA (Japan International Cooperation Agency), AIIB (Asian Infrastructure Investment Bank), and the OPEC Fund for International Development (OFID). Section 4 (Sriperumbudur to Singaperumalkoil) is complete; Sections 2 and 3 are near completion; Section 4 complete and operational. Sections 2 and 3 nearing completion as of early 2026. Section 5 tender floated December 2025. Section 1 (Ennore to Thatchur) remains the most delayed section; full project completion now expected 2027.
Active Land Acquisition Across 30 Villages: What Chennai Peripheral Ring Road Land Buyers Must Check Before Any Purchase
Land acquisition for the CPRR is still in progress across sections that are not yet complete. Over 234 hectares are being acquired across more than 30 villages, affecting approximately 676 families. Section 1 (Ennore Port to Thatchur, 25.4 km) faces the sharpest delays: relocating 12 water tanks and rerouting heavy power transmission lines are blocking completion. Section 5 (Singaperumalkoil to Mamallapuram, 27.41 km) land acquisition is in its final stage, but tenders have not yet been floated; this section was upgraded from four to six lanes, which also expands the land footprint from the original plan.
The 60-meter ROW is the base corridor. Service road land acquisition is still underway across the entire 132.87-km alignment, meaning the effective footprint is wider than 60 meters in many sections. In stretches where the alignment crosses reserved forest land, TNRDC is processing land swap proposals; plots that border reserved forest areas near the CPRR alignment carry additional legal complexity that standard title verification will not capture.
The table below shows each section, its status, and the current land risk for buyers in adjacent villages:

Do not assume that because Section 4 is physically open, adjacent land is free from acquisition risk. Service road land acquisition runs the full length of the corridor; a plot that sits just outside the 60-meter main ROW may still be inside the service road acquisition band. Verify the survey number against the current TNRDC land acquisition notification, not just the main carriageway boundary.
Sriperumbudur to Mamallapuram: Which CPRR Corridors Carry Real Land Investment Value in 2025
Section 4 is the only fully operational section of the CPRR today; it runs through Sriperumbudur, which is already an established electronics and automotive industrial belt. Land there is not priced on future CPRR upside; it is priced on existing industrial demand. The real investment question is where the CPRR adds a new connectivity advantage to areas that were previously harder to access.
The table below shows the primary micro-markets along the CPRR alignment and the realistic land signal at each:

Singaperumalkoil is the most misread corridor on this alignment. Brokers market it as "Section 4 complete, so uplift is confirmed," but Section 5 (continuing south to Mamallapuram) has not yet reached tender stage; the Singaperumalkoil-to-Mamallapuram land play depends entirely on Section 5 progressing on schedule. The Mamallapuram corridor on the ECR (East Coast Road) is where the speculative premium is highest and also where the timeline is least certain; full completion of Section 5 is expected no earlier than 2026.
