Nacogdoches motorists are learning well about bottlenecks in the flow of traffic. Construction at SFA has led to the closure of Carolyn, Baker, and East College Streets, as well as the west lane of Clark Street. Slow moving traffic is common on Starr avenue where big trucks block the roadway. Nacogdoches Police Department's Sgt Greg Sowell said, "There's going to be a lot of delivery trucks, 18 wheelers, construction equipment. The public needs to be very mindful of these vehicles. There will be times these vehicles will be making an ingress or egress when there could be some traffic problems."
