A tractor trailer rollover closed the new ramp to the westbound 401 from Highway 3 early Tuesday.

OPP reported the collision around 7:30 a.m.

The ramp was closed shortly after and emergency vehicles remained at the scene for much of the day.

Police say no one was injured in the collision.

The ramp is expected was closed well into the afternoon for the cleanup, but re-opened shortly before 5 p.m.
