Changning District yesterday opened a pedestrian tunnel in Hongqiao that connects L’Avenue, a shopping and office complex, with Friendship Shopping Mall.

The tunnel is part of the district government’s plan to become a “world-class central business district.”

The 43-meter-long tunnel beneath Xianxia Road is one of four pedestrian tunnels planned to connect 10 shopping malls and office buildings in the area — by building an underground pedestrian system beneath the central business area.
