 In July 1930, work began on sinking piers for the 4,200-foot-long bridge with a 240-foot central span.On completion in November 1931, work trains carried the steel rails across the bridge to lay of track for the Lulu Island industrial branch line.This comprised two north-south lines from west of the new bridge to connect with the remnants of the original east-west line at the south arm, with a scheduled completion date for the $2m project before yearend.
