The Adirondack Park Agency has approved plans for two adjacent cell towers to fill a hole in phone service along the highway connecting Albany with Montreal.

The agency board authorized Verizon’s 75-foot tower resembling a tree and T-Mobile’s 85-foot pole, both near the High Peaks Rest Area in North Hudson. The companies use different technologies.

The board also designated the western part of Lows Lake wilderness and the eastern end a primitive area, which abuts private land, a dam and an area where Boy Scouts can keep using motorboats. Most surrounding land is state-owned. The designations prohibit public use of motors on the western Adirondack lake.

The agency previously banned floatplanes from Lows Lake after 2011. The board took the actions last week.
