National Highway 48 passes through Ahmedabad and connects it with New Delhi and Mumbai. The National Highway 147 also links Ahmedabad to Gandhinagar. It is connected to Vadodara through National Expressway 1, a 94 km (58 mi) -long expressway with two exits. This expressway is part of the Golden Quadrilateral project.

In 2001, Ahmedabad was ranked as the most-polluted city in India out of 85 cities by the Central Pollution Control Board. The Gujarat Pollution Control Board gave auto rickshaw drivers an incentive of ₹ 10,000 to convert the fuel of all 37,733 auto rickshaws in Ahmedabad to cleaner-burning compressed natural gas to reduce pollution. As a result, in 2008, Ahmedabad was ranked as the 50th most-polluted city in India.
