A fire on Route 40 damaged an Aberdeen building and slowed traffic late Monday afternoon, according to local police and fire reports.

The fire was reported at 4:37 p.m. in the 100 block of South Philadelphia Boulevard, near the MARC/Amtrak station and the overpass that carries Bel Air Avenue over the train tracks.

The fire was brought under control by 4:50 p.m. and no one was injured in the blaze, Harford County Volunteer Fire & EMS Association spokeswoman Jenn Chenworth-Price said.

Smoke was billowing from the Silbaugh Memorials building, according to an Aberdeen police photo. The business sells gravestones.

The property was a "home that was turned into an office," Chenworth-Price said. The occupants were able to escape. Chenworth-Price did not know how many people were in the building.

The cause of the fire, which started in the attic area, remained under investigation Tuesday morning, according to a notice of investigation from the Maryland State Fire Marshal's Office.

Damage is estimated at $30,000, according to the notice of investigation.

The first units on the scene reported a "working building fire," according to Harford County emergency radio dispatches.

Forty firefighters from the Aberdeen Fire Department, Aberdeen Proving Ground Fire Department, Susquehanna Hose Company of Havre de Grace and Level Volunteer Fire Company responded, according to the notice of investigation.

Route 40 was briefly closed to eastbound traffic, Aberdeen Police reported.
