WHITMORE LAKE, Mich. -

Southbound U.S.-23 is shutdown at North Territorial Road due to a crash.

The crash is on the U.S.-23 southbound ramp to eastbound M-14. This is considered a hazmat situation because the wrecked semi truck was carrying combustible materials.

At least one other vehicle -- a sport utility vehicle -- was involved in this crash. It's not known if anyone was seriously injured.

The ramp from westbound M-14 to northbound U.S.-23 also is closed.
