SEATTLE — Skanska is expanding its infrastructure construction and civil engineering operations to the Northwestern United States, where it recently received a $115 million contract to work on a section of the Alaskan Way Viaduct in Seattle.

“It is our strategic intention to also become established within infrastructure construction and civil engineering in this expansive region, where we have a long tradition in building construction,” said Mike McNally, executive vice president of Skanska. “We have now secured our first road contract and I am certain that we will expand in this market.”
