To carry out such works, the expressway near to the Lonavala exit till Khopoli exit was closed from 10 am to 5 pm for 10 days after the landslide near Adoshi tunnel on 18 July 2015 which took three lives and halted the traffic for two months.
The boulders fell on both carriageways which caused huge diversion of traffic towards the old highway.
MSRDC has decided to extend the Mumbai Pune Expressway from the current endpoint of Kalamboli near Panvel and to extend it till Sion in Mumbai.
Thereafter tenders for widening of Khandala and Lonavala-Khandala bypass works were invited.
The tenders were received on 24 August 1998 and orders were issued on 4 September 1998.
This tunnel contains only a half part of the expressway which goes from Pune to Mumbai.
The Mumbai-Pune carriageway skirts the eastern edge of the tunnel while the Pune-Mumbai carriageway traverses the 230 m long tunnel.
The toll collection data is kept as secret as per the RTI raised by Vivek Velankar.
The Expressway contract with the Ideal Road Builders (IRB) has been uploaded but the toll collection details are not there.
The Expressway has witnessed a large number of auto accidents, attributed to human errors and the large volume of traffic.
In the first 10 years since its opening, there were 1,758 accidents with more than 400 fatalities.
In 1990, the Government of Maharashtra appointed RITES and Scott Wilson Kirkpatrick to carry out feasibility studies for the new expressway to be operated on toll basis.
