Construction spending fell in July for the first time in four months, the Commerce Department said Tuesday.
The 0.9% drop was the biggest decrease in a year and followed a 0.4% increase in June, Commerce said.
Economists had forecast a 0.4% increase, Bloomberg reported.
Private non-residential construction spending decreased 0.9%, while single-family homebuilding outlays climbed 1.5%.
Public construction dropped 0.4% from the prior month.
Construction spending can boost demand for trucking services because spending increases the number of shipments of goods and building materials.
