The upgrade of the National Exhibition and Convention Center to prepare for the  China International Import Expo will be finished before September. Meanwhile, 12 road constructions around the center will be finished before the expo opens in November, said Shanghai Municipal Investment Group which is in charge of these road works.

The section of S26 highway leading to Shanghai, Zhuguang Road and north section of G15 highway will be the three major roads to ease the traffic pressure of cars entering the city from Zhejiang and Jiangsu provinces.

The renovation of G15 highway, the major north-south route in the west of Shanghai, is due to be finished by the end of September.
