The OMR stretch from Thoraipakkam to Sholinganallur lies mostly in the Greater Chennai Corporation’s Sholinganallur zone (Zone 15). Under the state gazette, that zone covers wards 192 to 200. Corporation lists place Thoraipakkam’s schools in ward 193, Okkiyam Thoraipakkam’s Secretariat Colony in ward 194, and Sholinganallur’s OMR government higher secondary school and TNHB layout in wards 198 and 199. Areas north of Thoraipakkam, such as Perungudi, are in Zone 14.

The corridor is largely apartments, with IT parks on the main road and older villages behind them. Its civic problems are of that kind too: water supply, sewer lines, traffic and drainage into the Pallikaranai marsh.

Civic offices

Zone 15 office: No. 120, Rajiv Gandhi Salai (OMR), Chennai 600119, according to the e-Sevai centre list. The same list has a revenue e-Sevai centre at the Revenue Inspector complex on Nedunchezhiyan Salai, opposite Infosys, and division offices at Chandrasekaran Avenue in Okkiyam Thoraipakkam (ward 194), Kannagi Nagar (ward 195) and Semmancheri (ward 200).
Health: find your nearest Corporation urban health centre through the GCC health department or your ward office.
Police: parts of the corridor fall under the Adyar police district of the Greater Chennai Police, which includes the Semmancheri and Kannagi Nagar stations, DT Next reported in 2019. Use the Kaaval Uthavi app to find yours.
Post and registration: use India Post‘s locator, and check your flat’s sub-registrar office on TNREGINET before signing a sale deed.

Note the Assembly map too. Sholinganallur constituency belongs to Chengalpattu district and had more than 5.36 lakh voters before this year’s election, DT Next reported, making it one of the largest in the state.

Transport and the metro

There is no rail line on this stretch yet. The nearest MRTS stations are Taramani and Perungudi to the west. Most residents rely on MTC buses along OMR, office shuttles and cabs.

Two Phase 2 metro corridors will serve the area. Corridor 3, from Madhavaram to SIPCOT, runs elevated along OMR. CMRL’s diversion list names Thoraipakkam Junction, Kandanchavadi Junction and the Taramani ramp among its sites. Corridor 5 ends at Sholinganallur after coming in via Medavakkam. CMRL has cast all 3,126 precast elements for the Ullagaram to Sholinganallur section of Corridor 5, including its final U-girder, DT Next reported on 14 October. Girder erection and station entries come next. CMRL’s status page gives end-2028 as the completion date for Phase 2.

A road redesign will follow. CUMTA plans a makeover of 25 km of OMR from Madhya Kailash to Kelambakkam and 7.4 km of the Pallavaram to Thoraipakkam radial road. It covers bus lanes, footpaths, cycle tracks, utilities moved underground and better storm drainage, DT Next reported. A project report is expected by January 2027, with the contract possibly awarded in June 2027. Night closures for metro sewer work, such as those between Tidel Park and Indira Nagar in early September, will keep coming.

Water, sewers and drainage

On 14 October the Chief Minister laid the foundation stone at the Sholinganallur Metro Water pumping station for a ₹3,108.55 crore Ring Main System. It will have about 158 km of pipelines linking treatment and desalination plants, is funded by the Asian Development Bank and is due by 2031, DT Next reported. Until then, supply can be cut when desalination mains are worked on. A 1,400 mm pipe realignment on TNHB-A Main Road in ward 199 cut desalinated water to zones 13 and 14 for ten days in September, DT Next reported.

Sewer work is still catching up with the flats. In Secretariat Colony, Thoraipakkam, Metro Water’s underground drainage project had left roads slushy for over a year by August. The Corporation can relay roads only after Metro Water issues an NOC, DT Next reported.

For floods, the key channel is Okkiyam Maduvu, a 2.65 km link that carries marsh water to the Buckingham Canal. Desilting began in late July to clear water hyacinth, DT Next reported. Sholinganallur zone has more than 20 of the city’s 219 waterlogging-prone spots this year, News Today reported. The government higher secondary school on OMR in Sholinganallur is a Corporation relief centre.

Other things to know

Residents further south, from Navalur to Kelambakkam, have complained of a recurring evening chemical odour. The TNPCB had not identified its source by August, DT Next reported. Parks are scarce. The Corporation’s fitness parks list includes the Secretariat Colony 1st Main Road park in Okkiyam Thoraipakkam and the TNHB B-6 park in Sholinganallur.
