 Work on Binnie's design began, but was beset by problems. Leading architects condemned the design, with Arthur Beresford Pite describing it as "a would-be Gothic architectural form of great vulgarity and stupid want of meaning", and T G Jackson describing the bridge designs as a sign of "the utter apparent indifference of those in authority to the matter of art". Plans to build large stone abutments had to be suspended when it was found that the southern abutment would block the River Effra, which by this time had been diverted underground to serve as a storm relief sewer and which flowed into the Thames at this point. The Effra had to be rerouted to join the Thames to the north of the bridge. After the construction of the foundations and piers it was then discovered that the clay of the riverbed at this point would not be able to support the weight of a concrete bridge. With the granite piers already in place, it was decided to build a steel superstructure onto the existing piers, and a superstructure 809 feet (247 m) long and 80 feet (24 m) wide was designed by Binnie and Maurice Fitzmaurice and built by LCC engineers at a cost of £ 437,000 (about £ 42,390,000 in 2016).
