CHICAGO (CBS) — A 6-inch gas main broke in front of a high-rise in the Uptown neighborhood Tuesday morning, prompting authorities to evacuate the area.

A construction crew hit a 6-inch gas main around 11 a.m. in front of the Buena Pointe condo tower at 4350 N. Broadway.

The Fire Department evacuated people nearby as a precaution, and called a Level 2 Hazmat response.

The 10-story, 92-unit condo tower is in the middle of a densely-populated area where Broadway, Montrose Avenue and Sheridan Road come together.

The scene was secured by 11:25 a.m. No one was injured.

The gas leak also halted the CTA Red Line ‘L’ between the Wilson and Addison stops as buildings were evacuated. Service had been restored by 11:40 a.m., but delays were still reported on the Red Line, according to the Sun-Times Media Wire.

It was not immediately learned how many buildings had to be evacuated.
