The excessive heat is likely the reason a small section of Highway 50 buckled this afternoon.

One eastbound lane near the 15th Street exit is closed for repairs. While spokesman Dennis Keaton says buckling is not expected to become a widespread problem, Cal Trans officials are keeping an eye on the situation.

Because of the rain last week and the high temperatures this week, any road areas that have cracking could be subject to buckling, Keaton said. But it's not something that drivers need to be overly worried about.

Most of the structures are inspected on daily schedules, Keaton said. So there isn't a need to be too concerned that this will happen again.

The isolated case on Highway 50 should be repaired within 24 hours.
