Two Andover companies are relocating across town to River Place at I-93.

Casa Systems, a cable edge technology company, leased 16,086 square feet of office and R&D space on the building’s first floor. The company is relocating its corporate headquarters from 10 New England Business Center in Andover, expanding its office by 5,000 square feet.

uReach Technologies, a communications solutions company, leased 13,006 square feet of office and R&D space, also on the building’s first floor. The technology company is relocating from 200 Bulfinch Drive in Andover.

"River Place at I-93 is a very attractive location in the I-495 market, with its excellent location, superb highway visibility and amenities," said Brian McKenzie, partner, Richards Barry Joyce & Partners. "The building improvements made by CrossHarbor Capital Partners and, as importantly, their ability to react quickly to the tenants’ requirements in an unstable economic environment were key contributors to the success of attracting these two tenants."

Casa Systems was represented in the transaction by NAI Hunneman. uReach was represented in the transaction by Robert Byrne, assistant vice president of Richards Barry Joyce & Partners.

Byrne and Brian McKenzie of Richards Barry Joyce & Partners represented CrossHarbor Capital Partners in the leases. RBJ is the exclusive leasing agent for River Place at I-93, according to a statement.
