For millennia, Sichuan's rugged and riverine landscape presented enormous challenges to the development of transportation infrastructure, and the lack of roads out of the Sichuan Basin contributed to the region's isolation. Since the 1950s, numerous highways and railways have been built through the Qinling in the north and the Bashan in the east. Dozens of bridges [[Yangtze River bridges and tunnels|across the Yangtze]] and its tributaries to the south and west have brought greater connectivity with Yunnan and Tibet.

===Airports===
[[Chengdu Shuangliu International Airport]] is the 4th-busiest airport in mainland China. It was among the world's top 30 busiest airports in 2015, and the busiest in western and central China. It was also the fifth-busiest airport in terms of cargo traffic in China in 2013. Chengdu airport is the hub of [[Sichuan Airlines]], [[Chengdu Airlines]], [[Shenzhen Airlines]], [[Tibet Airlines]], [[China Southern Airlines]], [[China Eastern Airlines]], [[Lucky Air]], and [[Air China]]. Alongside Shuangliu Airport, [[Chengdu Tianfu International Airport]] has opened in 2021.

Chengdu airports are also 144-hour transit visa-free airports for foreigners from 53 countries.

===Expressways===
On 3 November 2007, the Sichuan Transportation Bureau announced that the [[G93 Chengyu Ring Expressway|Suining-Chongqing Expressway]] was completed after three years of construction. After the completion of the Chongqing section of the road, the {{cvt|36.64|km|}} expressway connected [[G42 Shanghai–Chengdu Expressway|Chengdu-Nanchong Expressway]] and formed the shortest expressway from [[Chengdu]] to [[Chongqing]]. The new expressway is {{cvt|50|km|}} shorter than the pre-existing road between Chengdu and Chongqing; thus journey time between the two cities was reduced by an hour, now taking two and a half hours. The Sui-Yu Expressway is a four-lane overpass with a speed limit of {{cvt|80|km/h|}}. The total investment was 1.045 billion [[Chinese yuan|yuan]].
