Heads up 
As a part of their annual tree pruning program, National Grid has hired Nelson Tree Service to conduct isolated tree pruning along Cummings Road, Dunstable Road, Westford Road, Kendall Road, and Locust Ave. 
This work is designed to clear areas around National Grid’s infrastructure to prevent falling limbs from interrupting electric service.
