The Intercounty Connector is turning out to be more popular than expected. The new highway, which environmentalists fought for decades before its opening this year, attracted an average of about 21,000 vehicles per day — just over the 20,000 officials expected.

About 326,000 cars took the ICC during the highway’s first two weeks of operation after tolls were instituted along its newest section. Officials earlier predicted that the highway would see about 20,000 cars a day right after tolls kicked in and wouldn’t see 30,000 cars until June.
