RCMP investigating a major collision on a busy northern Alberta highway Wednesday morning said Thursday that the two people killed in the crash were from the Edmonton area.

Wood Buffalo RCMP said two Edmonton men died, after two transport trucks collided head-on on Highway 63, south of Fort McMurray near Mile Marker 173 just before 9 a.m. Wednesday.

One of those transport trucks was carrying diesel fuel at the time, and the collision sparked a fire.

Initial reports on the crash indicated a number of other vehicles were involved in the crash, police later said five vehicles swerved to avoid the collision and ended up in the ditch. No other injuries were reported as a result of the crash.

The affected section of Highway 63 was closed for the rest of the day as RCMP conducted their investigation.

The roadway finally reopened early Thursday morning after the 21 hour closure.

RCMP are investigating the cause of the collision.
