National Grid will be upgrading its electrical lines this fall along the Northern Strand Trail, possibly closing the trail for a few minutes at a time if necessary.
Work this week will be done in Malden at a substation off Broadway, near the CVS and Playful Paws dog daycare center. Next week work will be done from Broadway to Clapp Street in Malden. National Grid employees and signs will alert those using the trail to ensure public safety.
The trail is expected to remain open during this time but may need to close for short periods when equipment is moved.
