(Dodge County) The Wisconsin Department of Transportation says to plan ahead, buckle up and be patient while travelling over the July Fourth holiday. Officials say Wednesday is one of the busiest travel periods of the year and for drivers to expect higher traffic volumes than normal. Due to the influx of vehicles most highway construction projects will be suspended at noon Tuesday and will resume on Thursday. WisDOT Secretary Dave Ross says with a temporary halt on construction work, there will still be work zones and drivers must watch their speed and stay focused on the road ahead. He says the State Patrol and other law enforcement agencies will be out enforcing traffic laws and assisting stranded motorists. Other important reminders for safe travel include checking the 511 travel information system for accidents and delays, putting down cell-phones while behind the wheel and to move over for emergency vehicles. The Wisconsin Division of Motor Vehicle customer service centers will be closed on the fourth. Citizens can conduct business online 24/7 at www.wisconsindmv.gov.
