Houston gas prices are expected to climb higher on July 4, hitting $3 a gallon at some stations as drivers gear up for road trips on one of the year’s busiest travel days.

The price of regular unleaded in the Houston area is expected to average $2.69 a gallon that day, according to GasBuddy, which tracks fuel costs nationwide. That’s the highest July 4 average since 2014, when crude oil prices topped $100 a barrel and drove the average cost of gasoline to $3.48 a gallon.

As a result, GasBuddy anticipates that drivers will spend $1.02 billion more at the pump during the first four days of July.
