SACRAMENTO - A big rig caught fire along eastbound Highway 50  in Sacramento Friday morning. 

The fire started around 8:15 a.m., possibly from a tire on the truck that had caught fire. 

As the big rig, which was hauling wood pallets, began to burn, the driver pulled over to the right-hand side of the highway, just east of the Interstate 5 connector. 

As a result of the incident, all lanes of eastbound Highway 50 west of 15th Street had been closed, but lanes #1 and #2 were reopened, as well as the 15th Street offramp, later Friday morning. 

Al lanes were reopened a little before 3 p.m. 

Some residual traffic delays are still expected.
