The Texas Department of Transportation says road construction is to blame for traffic delays on the highways this holiday weekend. The delays on I-20 are concentrated in the westbound lane of the Interstate from Barber road to Highway 271 and in the eastbound lane from Jim Hogg road to FM 2015. Earlier today, traffic was backed up anywhere from five to nine miles in both lanes, meaning up to a four hour delay on the highway. TXDOT says the traffic jam could last throughout the holiday weekend. For the latest on road delays in the smith county area, call the TXDOT information line at 866-633-8106. The good thing about the information line is, it also gives you detour options.
