Firefighters worked Saturday night to extinguish a three-alarm blaze at a Catonsville Days Inn that displaced 160 guests and shut down a section of Route 40 and exits from the Baltimore Beltway, police and fire officials said.

Crews were called at 8:20 p.m. to the 5700 block of the Baltimore National Pike for the fire, which began in the seventh floor of the hotel, fire officials said. The fire went to a third alarm in about 20 minutes and continued to burn for more than two hours, officials said.

Two people were taken to a local hospital for minor injuries, said fire spokeswoman Elise Armacost. She said the hotel was working to relocate guests to other establishments.

As of 11:15 p.m., eastbound Route 40 remained closed, as was Exit 15 off 695 to Route 40.
