China is planning to spend $6.3bn to upgrade a stretch of the 1,900km G50 motorway between Shanghai and Chongqing, the World Highways website reports.
The work will be carried out between the cities of Wuhan and Yichang in Hubei province in central China.
A 266km length of the four-lane dual carriageway will have extra lanes, as well as ancillary infrastructure such as service stations, parking and maintenance areas, and toll booths.
Some 27 interchanges will have to be rebuilt or added to accommodate new connecting roads.
Several other major road schemes are underway, or have reached the tendering stage in China.
The 114km Qionglai–Yingjing Expressway Project, worth nearly $3.9bn, has been awarded to several civil engineering companies based in central China’s Sichuan province
Bidding has begun for an eight-lane stretch of the South Lake Link in the Shanghai conurbation. This $1bn project will connect Zhapu and Suzhou, with three major interchanges, a service area and four tolling stations.
Bidding is also underway for a 202km stretch of the highway between Subei and Ruoqiang in Gansu Province in China’s far northwest. This is expected to cost nearly $1.7bn and will be procured as a public–private partnership (PPP).
Finally, a stretch of the Chao Huang Expressway is out for tender under the PPP form. This is a 48-month project with an estimated cost of $1.4bn. The winner will build four tunnels and 18 bridges on a new road that will link the Shanghai–Wuhan Expressway and the Mingshan Expressway.
