The ICC opened to the public on Feb. 23, but drivers did not have to pay a toll until Monday.
According to the Maryland Transportation Authority, about 2,000 vehicles traveled the ICC Monday between 6 a.m. and 9 a.m. Those are considered peak times during the morning rush hour. However, when the road was free, more than 5,000 drivers used the ICC during the same hours.
A trip on the ICC costs $1.45 during the morning and afternoon rush hours. It costs less during off peak and overnight hours.
The first stretch of the roadway opened last month and rest of the ICC is expected to open late this year or early next year. When its complete it will connect I-270 in Gaithersburg with I-95 in Laurel.
