What reported cost did the Leverett Circle Connector Bridge have when it opened in 1999?
The Leverett Circle Connector Bridge is a four-lane steel box-girder bridge across the Charles River in Boston. The Massachusetts Turnpike Authority, which delivered it within the Central Artery/Tunnel project, reported a USD 22.27 million cost and an October 1999 opening. Its project page describes an 830-foot bridge with a 380-foot main span. The much longer 1.7-mile connector-road route must not be mistaken for the physical bridge length or included without a separate cost source.
Reported project cost
$22.27 million
Cost basis: 1999
The short answer
$22.27 million
The Massachusetts Turnpike Authority listed USD 22.27 million for the Leverett Circle Connector Bridge and identified October 1999 as its completion month. This is an owner-reported historical figure, not an inflation-adjusted amount.

Cost scope
The amount belongs to the 830-foot four-lane bridge across the Charles River. It does not price the whole 1.7-mile connector route, the adjacent Leonard P. Zakim bridge or the entire Big Dig.

Reading the data
How to interpret the figure
Cost, bridge length, main span and opening month are stated directly on an archived Massachusetts Turnpike Authority project page. The USD figure needs no exchange-rate conversion or inflation adjustment. The old 1.7-mile metric was excluded because it describes the road connector rather than the physical bridge.
