UPPER MERION TWP., Pa. (WPVI) -- Traffic is moving again after an overturned tractor trailer shutdown a major interchange in Upper Merion Township, Montgomery County.
The crash happened at 5:39 a.m. Thursday on the ramp from I-76 West to Route 202 South.
Police say the 18 wheeler was traveling too fast and lost control as it was exiting the ramp and about to merge with southbound Route 202.
As it tipped over, its load of metal and other debris fell out and blocked Route 202 southbound.
The driver of the big rig was not injured.
Large yellow 25 mile-per-hour signs mark the 1600 foot long ramp as traffic enters the ramp's first curve. The ascending roadway then straightens as Route 422 traffic departs to the right, then the roadway curves again as it descends and lines up with Route 202.
PennDOT says in the wake of today's crash the agency will consider if there needs to be more speed advisory signs on the ramp.
