At 730 metre in length, the Chinchwad grade separator is the second longest of the three. It is nine metre wide and includes in its range two chowks -- Mahavir and Shivaji. The Akurdi grade separator is 560 metre in length and nine metre in width. The work on both the grade separators started in March 2006, three months after Pimpri grade separator was thrown open to the public. The Pimpri grade separator which is the longest at 795 metres was constructed at a cost of Rs 18 crore, but has failed to remain motorable.

The construction of both Chinchwad and Akurdi grade separators have generated a lot of heat, especially after their costs jumped astronomically. The Akurdi one was initially set to cost Rs 14 crore, but later the civic adminstration said it would cost Rs 29 crore. Similarly, the Chinchwad grade separator has been constructed at cost of Rs 39 crore. Chief Minister Vilasrao Deshmukh had stalled the construction of the Chinchwad grade separator after Congress leader Srirang Barne raised certain objections. A few months later, Deshmukh lifted the stay after hearing out the civic adminstration.

With the construction of the two grade separators and the one already in place at Pimpri, the time taken to reach Nigdi from Bopodi on the Pune-Mumbai highway will come down drastically. Then municipal commissioner Dilip Band, during whose tenure the Pimpri grade separator was completed and two other grade separator work started, had maintained that it would take eight minutes to travel from Bopodi to Nigdi once grade separator work is completed. After Bopodi, there will be only one major signal -- that is at Nashik Phata chowk. Here too, the PCMC has planned an overbridge which will fly over road, rail and river and is being described as the unique one. Despite its inauguration over four years ago, the bridge work is yet to get cracking.
