Construction has begun on a 2.7 million cubic foot expansion of a Henningsen Cold Storage Co. site in Portland that’s expected to be complete in May.

Built in 2008, the facility serves as a distribution center and manufacturing support facility for companies requiring frozen and refrigerated warehousing in the Pacific Northwest.

Upon completion, it will offer 7.9 million cubic feet of space and more than 30,000 pallet positions — up 13,000 overall.

“We are not sure what the product mix will be yet, but fresh fruits and vegetables are a possibility,” said Bill Daniel, spokesman for Henningsen Cold Storage Co.

The facility will have quick access to interstates 84 and 205, according to a news release.

“We are simply staying ahead of the curve with our customer growth,” Michael Henningsen, chairman and president, said in the release.

Besides Oregon, the company has facilities in Idaho, North Dakota, Oklahoma, Pennsylvania and Washington.
