Construction spending climbed 0.4% to a seasonally adjusted estimated annual rate of $842.1 billion in May, the Commerce Department reported Wednesday.
The June rate rose from the revised May estimate of $838.3 billion, originally reported as $830 billion. The June figure was 7.0% above the June 2011 estimate of $786.8 billion, and was the largest since it was $832.6 billion in December 2009.
Economists polled by Thomson Reuters had predicted a 0.4% increase in the rate from May to June.
