While all roads lead to the Sadras Tiruttani highway, minor roads in Tiruttani have been wrongly marked as being part of the highway. M P Sivagnanam street, Akkaiah Naidu street, Arakkonam Road, Cudappah trunk road etc are names that feature commonly on shops and establishments in Tiruttani, but these are not visible on the map.

This road is not a single road - it consists of two roads - each a one way, separated by a divider. One is Gangadhara Chetty Road, the one that leads towards Neelakantan Circle and the other is - I am guessing - Annaswamy Mudaliar Street, the one leading away from Neelakanthan circle if you're coming from St.John's Church Road if you take a right at Raghavendra Swamy Mutt circle. You can check the address of Odukathur Mutt - http://www.odukathurmutt.org/contact/contact1.html - where the address says "Gangadhara Chetty Road". I have added it to the map anyway - but this needs to be confirmed.

Peenya 2nd stage is this area. I am sure that there's a bus depot called Peenya 2nd stage around here somewhere.

Health and Glow is wrongly marked as being after the Navarang bus stop. It's actually before the bus stop. Either the bus stop's position or the store's position must be changed

Multilingual translations read "Kaveri" for Telugu, Malayalam and Bengali. Needs fixing. This is Kollidam, a distributary of the Kaveri, not the Kaveri.

Pronounced Kollidam - with emphasis on L and d so KoLLidam, not KolliDam or Kollidham or KolliDham

Prestige Wellington Park seems to have been marked on the wrong side of the road

There's no road here! A drain runs here. All these roads - MEI Colony 1st cross, 2nd cross and 3rd cross are all dead-ends. The road adjoining the Ganapathi temple is not a dead end, it leads to Vidhanasoudha Layout.

This is not Peenya 2nd Stage!

Area can be marked for Diacon hospital. Building next to it is Kanva mart

The Cauvery river seems to be out of place. I can't see it on the background imagery - it's either offset by a bit or it doesn't exist here or is the dry bed not visible? It also seems to be cutting through lots of things.
