Firefighters knocked down a fire burning north of Colorado Springs along Interstate 25 south of Baptist Road.

A Gazette photographer observed fire crews putting out hot spots and officials reopening southbound I-25 south of Baptist Road shortly after 2 p.m. on Monday.

Monument Fire District Chief Andy Kovacs said the cause of the fire is under investigation.
