Gas prices in Philadelphia rose to a record-breaking $5.01 per gallon on average in Philadelphia on Saturday. It rose 8 cents overnight and $1.85 over the past year. The pent-up demand for travel in the wake of the pandemic and the war in Ukraine are both contributing to the high prices, which are expected to continue increasing. This is due to new sanctions the European Union is leveling against Russia and China's emergence from its latest COVID-19 lockdown.
