A strange material glazed the surface of a northeast Calgary road on Tuesday, leaving crews baffled at what it might be.

The Calgary Fire Department (CFD) responded to the 7100 block of 80 Avenue N.E. after a 911 call alerted them to an “oil spill or some substance [that] ran the length of two blocks” at around 2:45 p.m.

Firefighters, police and Calgary roads were called to the scene.

Police closed westbound lanes until the mess was cleaned up.

The fire department said a construction company came back to the scene and took responsibility, saying the spill was pond scum.
