The Sion Panvel Expressway is a 25 km Indian highway located entirely in the state of Maharashtra, that connects Sion in Mumbai with Panvel, via Navi Mumbai. It is one of the busiest and most important roads in the Mumbai Metropolitan Region (MMR), and connects Mumbai with the city of Pune. The National Highway 4 and Mumbai Pune Expressway begin at the eastern end of the expressway, at Kalamboli junction, near Panvel. The highway is also used by vehicles traveling towards Mumbai from Konkan and Goa.
As of September 2014, the stretch of the highway east of Vashi Bridge within the city of Navi Mumbai has been fully widened and concretized to 10 lanes (5 lanes in each direction). New flyovers have been built at Sanpada railway station, Nerul, Uran phata and Kamothe. A toll plaza built between Kamothe and Kharghar for recovering the construction cost was controversially opened on January 6, 2015 after much delay as the BJP-led Maharashtra state government admitted that it was not in a position to abolish the toll. Heavy traffic snarls were reported in the initial days as workers of Maharashtra Navnirman Sena vandalized the toll booths. One-way toll for motor vehicles has been set at ₹ 30.
