Listeners are reporting slowed traffic in the westbound lanes from Caddo Mills to FM 35 in Royse City.
The slow-go appears to be the result of a disabled tractor-trailer blocking the roadway. Traffic is being diverted to the service road as crews continue to clear the interstate.
Details on the causal accident are unclear, but seems to have begun to affect travelers as early as 4:00 this afternoon.
