Asphalt and concrete roadways are expanding and cracking and even Interstate 5 has been impacted amid a heat wave that has sent temperatures soaring to dangerous levels. "There have been several instances of road impacts across Western Washington today, including along I-5 at times," the National Weather Service's Seattle office wrote on Twitter. "Additional impacts likely tomorrow with another day of extreme heat. Remain vigilant on your commutes!" A state trooper shared images on social media of a damaged highway near Everson, Washington, about 10 miles south of the Canada border. "State Route 544 milepost 7 near Everson, Wa is currently closed," read the message from the Washington State Patrol District 7. "The asphalt roadway is buckling and unsafe for travel. WSDOT is advised and detours are currently being set up."
