HARRISBURG â€“ Pennsylvanians will see $2.1 billion worth of highway and bridge improvements this year, $600 million more than originally anticipated due to the state’s new transportation plan. Representatives from PennDOT and the Pennsylvania State Police today reminded motorists to drive carefully through the hundreds of work zones they’ll encounter this construction season. PennDOT also reminds all drivers to pay close attention to flaggers and signs. Motorists should maintain a safe distance around vehicles and use four-way flashers when stopped or traveling slowly. Drivers are also reminded to turn on their headlights in posted work zones and those who donâ€™t face a $25 fine.
