TRENT, S.D. (AP) -- Hot weather caused the concrete to buckle on Interstate 29 in east central South Dakota, causing headaches for motorists returning home from Fourth of July activities.
The Highway Patrol says about half a dozen vehicles suffered flat tires or damage to their undercarriages on Sunday before crews could fix the problem on the northbound lanes near the Trent exit.
Officials with the patrol and local fire departments alerted motorists about the hazard while the work was done. Permanent repairs will be done later.
