SAN ANTONIO -

Portions of a San Antonio highway were closed after a tractor-trailer carrying 40,000 pounds of limes overturned Thursday, sending much of its cargo across the roadway.

Ramps from Interstate 37 to U.S. 90 south of downtown were reopened Thursday afternoon, hours after the rig toppled over when its load shifted as it exited I-37. The accident cause extensive delays for morning commuters. Police say the truck driver and a passenger were not seriously hurt.

Efforts to reopen the ramps were slowed by the number of limes strewn around the accident site.
