The Mumbai to Pune Expressway, (officially known as the Yashwantrao Chavan Mumbai to Pune Expressway) is India's first six-lane concrete, high-speed, access controlled toll expressway. It spans a distance of 94.5 km (58.7 mi) connecting Mumbai to Pune, the administrative capital of Maharashtra and the financial capital of India, with Pune, an industrial and educational hub. The expressway, which was fully operationalized in 2002, introduced new levels of speed and safety in automobile transportation to Indian roads. It is one of India's business roads.
The expressway has reduced the travel time between the cities of Mumbai and Pune to approximately 1 hours 50 mins.[citation need] For most practical purposes, it has replaced the older Mumbai to Pune stretch of the Mumbai-Chennai National Highway (NH 4), which had become extremely congested and accident-prone overtimes. The expressway starts at Kalamboli (near Panvel), and end at Dehu Road (near Pune). It cleaves through the scenic Sahyadri mountains ranges through passes and tunnels. It has six interchanges: Sheung, Chowk, Khalapur, Lonavala, Kusgaon and Talegaon.
The expressway has three carriageways with four concrete lanes, each separated by a central divider and a tarmac or concrete shoulder on either side. Vehicles with fewer than four wheels and agricultural tractors are not permitted, although tractor trailers (semi-trailer rigs) are permitted. The expressway handles about 43,001 PCUs daily and is designed to handle up to 1,000,001 PCUs.
