The infrastructure upgrades are geared toward making the rural area into Haverhill's new industrial/business park, Pillsbury said. The area was once best known for illegal dumping and as a shortcut to New Hampshire.
The park includes land on both sides of the street along a stretch that is about a half-mile long.
It now has three businesses — Pella Windows & Doors, SAFC High Tech and WBC Extrusion Products Inc.
Construction of a complex containing what Pillsbury called industrial "flex space" is also underway. Called Hilldale Industrial Properties, it will offer businesses places for industrial uses such as warehousing and research and development.
The Biotechnology Council is not the first industry group to consider improved business ratings for Haverhill.
In November, Haverhill was ranked the 29th most attractive for high-tech companies looking to set up shop by the Massachusetts High Technology Council. The city ranked 244 out of 351 communities the previous year.
At the time, officials with the high-tech group said Haverhill's improved rating was a result of a faster permitting process for new commercial developments and the proximity of educated workers and new housing in the area.
