A proposed tower that would have improved the town’s cellular service is on hold.

HAVERHILL — A proposed tower that would have improved the town’s cellular service is on hold. The Zoning Board of Adjustment on Monday denied two of six variance requests for the project, putting its future in doubt. Developers Vertex Tower Assets LLC submitted plans to build a 166-foot, steel lattice tower at 12 Tee Pee Lane. The site was preferable because of its elevation and central location, and because it was already served by an access road serving another tower. Vertex Tower Assets had already secured one carrier, T-Mobile, and were reportedly in talks with another. The tower would have addressed the town’s notorious lack of cell service. The most recent Town Report recommends that Haverhill officials “Pursue 100 percent coverage of cellular communications and high-speed internet.” The ZBA refused to waive two zoning requirements: one requiring the tower be camouflaged, the other prohibiting tower construction within two miles of an existing structure.
