Police said they were called about 7:10am to reports of a single-vehicle crash on the highway near the intersection with Tekapo Canal Rd.
"No injuries were reported; however, the road does look to be completely blocked near the Tekapo Pukaki canal bridge."
A photograph posted on the Tekapo Community Facebook page showed a Mainfreight truck across both lanes of the highway bridge with the trailer on its side on the roadside barrier.
Fire and Emergency New Zealand shift manager Simon Lyford said the strong winds that caused havoc across much of the South this morning had blown the trailer over.
NZ Transport Agency Waka Kotahi early this afternoon said the winds were hampering efforts to remove of the trailer, but in an update about 2.45pm said the highway had reopened.
MetService earlier warned of very strong winds for much of the South Island today, and more wild weather to come through the week.
