By the early 1960s traffic congestion had become a problem and Lower Thames Street was widened over the next decade to form part of a significant new east–west transport artery (the A3211). The setting of the church was further affected by the construction of a new London Bridge between 1967 and 1973. The New Fresh Wharf warehouse to the east of the church, built in 1939, was demolished in 1973-4 following the collapse of commercial traffic in the Pool of London and, after an archaeological excavation, St Magnus House was constructed on the site in 1978 to a design by R. Seifert & Partners. This development now allows a clear view of the church from the east side. The site to the south-east of The Monument (between Fish Street Hill and Pudding Lane), formerly predominantly occupied by fish merchants, was redeveloped as Centurion House and Gartmore (now Providian) House at the time of the closure of old Billingsgate Market in January 1982. A comprehensive redevelopment of Centurion House (renamed Monument Place) began in October 2011 and the building was let in 2014. Regis House, to the south-west of The Monument, was redeveloped by Land Securities PLC in 1998.
