Cross Section - Overarch Span 
AHB Traffic Demand v. Capacity
Sunday morning - 3 traffic lanes northbound, 3 traffic lanes southbound 
In a 3 lane northbound/3 lane southbound configuration, the capacity of the Auckland Harbour 
Bridge is slightly greater than 5,000 vehicles per hour in each direction.  Based on typical Sunday 
traffic volumes, traffic demand would be greater than capacity between 11am and 2pm in the 
northbound direction, and 10am and 2pm in the southbound direction.  A strong communica-
tions strategy alerting motorists and heavy haulage to the event will assist in mitigating this by 
allowing vehicles time to plan to use alternate routes.
