The HZMB Main Bridge runs from the artificial island off Gongbei of Zhuhai to the eastern artificial island
for the tunnel section just west of the HKSAR boundary.
The project includes a 29.6 km dual 3-lane carriageway in the form of bridge-cum-tunnel structure
comprising a tunnel of about 6.7 km; two artificial islands for the tunnel landings west of the HKSAR
boundary; and associated works including civil and structural works, environmental mitigation, drainage,
electrical and mechanical, traffic control and surveillance system.
Construction of the HZMB Main Bridge commenced in December 2009 and the completion date is under
review.
