One of my friends studied at Saveetha Engineering College (SEC). According to him, there are two ways to reach the institution.
Keep in mind that if you need to travel some distance forward after crossing Saveetha college for a divider, it is not much of a distance.
If traveling by MTC bus is suitable for you, then board M66, 66, PP66, 566A and align at Poonamallee and change over to any other bus heading towards Sriperumbudur, Sunguvarchathiram and reach Saveetha college of engineering.
