PORTLAND -- Two crashes along Interstate 84 westbound caused a major traffic backup early Thursday morning.

At 5:17 a.m., a red SUV hit a guardrail near the merge from Interstate 84 westbound to Interstate 5 northbound, according to the Portland Police Bureau's crash log.

Then, at 5:53 a.m. near the Lloyd Center exit on I-84, two cars were involved a crash. No one was injured but the crashed backed up traffic until 7 a.m. when both crashes were cleared.

Traffic was backed up past the Lloyd Center exit during the peak of the problems causing headaches for early-morning commuters.

The first crash took place where the Oregon Department of Transportation recently made a major adjustment from two permanent lanes down to one.

The new lane change was made, starting on Monday, in an effort to cut down on crashes involving cars getting sideswiped at the merge onto I-5. But many drivers have complained that the change is too sudden and confusing.
