5 Dollars Benjamin Sheares Bridge

The Benjamin Sheares Bridge, completed in 1981, was Singapore's largest infrastructure project of its era and the first to span the mouth of the Marina Bay — a politically significant act of urban engineering that physically reshaped the city's southern coastline. Commemorating it on a circulating denomination the following year was a deliberate signal from the MAS that the bridge represented a new phase in Singapore's rapid modernization program under Lee Kuan Yew's government.

KM#22 is part of the second Singapore definitive series, which replaced the Orchid series beginning in 1985 — making 1982 strikes transition-era pieces that circulated only briefly before the redesign.
