The construction of this viaduct was the first step in a major redevelopment that followed a dramatic fire in 1866. The fire engulfed both 1831 Cotton Stores, which held a variety of highly flammable goods. The risk of collapse led to the immediate demolition of both warehouses after the fire. 

A second viaduct made it easier to handle the growing volume of goods traffic. The rail deck was supported by massive stone piers, cast-iron columns, brick jack arches and wrought-iron girders. The south face of the viaduct was equipped with hydraulic cranes to raise and lower goods to and from the Lower Yard. Hydraulic cranes and hoists survive in the 1830 Warehouse and on the top floor of the Main Building.  

A fireproof bonded warehouse was built on the north side of this viaduct in 1869.   One floor was reserved for cotton goods. The northern viaduct arches were used for workshops, stables and storing equipment and supplies.
