Poonamallee High Road is one of the city’s most heavily served bus corridors at its eastern end: 15B runs from Broadway to the Koyambedu bus terminus (CMBT) every 5 minutes on average, according to MTC route data. Further west, 53 and 101 carry on past Koyambedu through Maduravoyal and Vanagaram to Poonamallee, and 101 alone has 53 stops over 34.1 km.
This guide follows the road from Central to Poonamallee, lists which routes serve which section, and shows where the Green Line and the newly opened Yellow Line metro meet it. Frequencies in this guide are averages from the MTC route data on each route page and may be dated; check live timings in the Chennai One app or with MTC before you travel.
Central to Koyambedu
From Central the stop list is the same on every route: Dasaprakash, Taylors Road, Aminjikarai and Arumbakkam. 15B is the shuttle on this section. It runs 11.5 km from Broadway and ends at CMBT. 53 and 101 cover the same stops and continue west. 41C, the Anna Nagar West to Thiruvanmiyur route, uses the road only from Taylors Road to Aminjikarai before turning to Anna Nagar Circle and Thirumangalam.
101 is the most detailed of the stop lists. Between Central and Arumbakkam it names Park Station, Hotel Everest, Dinathanthi, Dasaprakash, KMC Hospital, Taylors Road, Aminjikarai Toll Gate, the Ampa Skywalk stop, NSK Nagar, DG Vaishnav College and Arumbakkam post office.
Koyambedu to Poonamallee
West of Koyambedu the road passes Nerkundram, Maduravoyal, Vanagaram and Velappanchavadi, then Saveetha Hospital, Karayanchavadi and Kumananchavadi before Poonamallee. 53 and 101 cover this whole stretch. M27ET comes from Vadapalani via Virugambakkam to CMBT and then follows PH Road through Maduravoyal and Velappanchavadi before turning to Thiruverkadu.

Stops on route 101, which runs 34.1 km from Thiruvottiyur through Royapuram, Central and the full length of PH Road to Poonamallee, per its route page.
Where the metro meets PH Road
The CMRL station list shows the Green Line leaving Central for Egmore, Nehru Park, Kilpauk, Pachaiyappa’s College and Shenoy Nagar before turning through Anna Nagar to Koyambedu, CMBT and Arumbakkam. So the metro runs close to the eastern half of PH Road, then leaves it after Shenoy Nagar.
The western end changed on 11 October 2026, when the Poonamallee to Vadapalani section of the Yellow Line opened. Its 11 stations include Poonamallee Bus Stand, Poonamallee Government Hospital, Karayanchavadi and Kumananchavadi, DT Next reported, with trains every 10 minutes at weekday peaks. The 101 stop list includes Karayanchavadi and Poonamallee Government Hospital stops, so riders at that end now have a rail option towards Porur and Vadapalani. For CMBT itself, CMRL’s feeder list names small bus S60 to Maduravoyal Erikarai via Nerkundram.
Timings to know
The 101 route page lists a first bus at 5.10 a.m. from Thiruvottiyur and 7 a.m. from Poonamallee, but the last buses are early: 5.53 p.m. from Thiruvottiyur and 7.58 p.m. from Poonamallee, with 110 to 120 minutes end to end. For evening trips, 53 or a change at Koyambedu is the safer plan. The 15B page gives a 5 a.m. first bus from both Broadway and CMBT. On the metro, the Yellow Line runs from 7 a.m. to 9 p.m., per DT Next.
