Somerville residents faced a nasty commute Thursday evening when a significant power outage in Cambridge led to major delays on the Red Line and gridlock on Cambridge streets.
Many Somerville residents work, study and shop in neighboring Cambridge, and those who work in Boston travel through that city on their way home.
The outage affected over 14,000 NSTAR customers in Cambridge, about 30 percent of the city, according to the electric company's power outage map, though according to Boston.com as many as 17,000 customers (34 percent) were without power at one point.
The outage started at around 4:30 p.m., Boston.com reported Thursday night, and it plunged much of the city, including the Harvard and MIT campuses, into darkness. By 7 p.m. the power was back on.
WCVB reported gridlock on Cambridge's dark streets, at the height of the evening commute, as police officers directed traffic by hand.
The Red Line experienced significant delays—one Twitter user reported an hour-and-a-half trip from Alewife to the Longfellow Bridge—according to the transportation authority. No T riders were stuck in tunnels, according to Boston.com.
