A mega-project that bridges the gaps

Traffic jams are nothing new in China, and during national holidays, the roads can get unbearably congested as millions travel across the country to be with family and friends.

"We were stuck in traffic for more than 15 hours during last National Day holiday," bus driver Xu Huiping said, gesturing to his colleague Li Zhiguang.

"Yes, a lot of cars and buses and a terrible traffic jam," agreed Li.
