Lesson
During the project preparation stage, it was anticipated that the project expressway would generate significant local socioeconomic development impacts. The expressway served not only as an important section of the transport corridor, but also as a vital link between Weinan and Xi'an and other neighboring regions. With growing traffic volume, it was observed that toll collection capacities at some exits were limited, which periodically caused long queues.

Lesson
The cost estimate of the toll system was overestimated at appraisal, and the actual cost was about one-third the appraisal estimate. The main reasons for this difference include (i) the network-based toll system arrangement resulted in cancellation of unnecessary equipment; and (ii) the cost estimate was made in 2000 and procurement was conducted in 2004, during which time the availability of more advanced information technologies contributed to a lower and more competitive actual cost.

Bidding of expressway civil works took place in early 2002 and the government approved the detailed design in mid-2002. Thus, among other factors, bidding which was not based on detailed design resulted in some significant variations for large structures with complicated geotechnical situations. Based on this experience and similar experience in other road projects, it would be appropriate to conduct in-depth detailed geotechnical investigations before finalizing bidding documents.
