A mandate from the federal government to reduce bandwidth on police, fire and other communication devices has left Island emergency responders struggling with spotty coverage at times this summer.

A portion of State Road in West Tisbury was closed to traffic for a short time Thursday afternoon after a truck carrying sand rolled over after trying to avoid a collision, police said. The driver of the John Keene excavation truck was transported to the hospital but was not seriously injured.

The Fourth of July holiday weekend proved a busy time for Island first responders, who responded to several calls, including a fire in a downtown Edgartown restaurant Saturday morning.

Two men were uninjured after the Jeep they were traveling in caught fire near the Big Bridge on Beach Road Friday afternoon. The Oak Bluffs fire department said their response was delayed because traffic did not yield to the emergency vehicles but they quickly extinguished the fire once they arrived.

Edgartown’s newest full-time police officers are ready for duty just in time for the department’s busiest day of the year, when the town fills up for the Fourth of July parade and fireworks. Zachary Townes and Curtis Chandler were sworn in Monday.
