ALAMEDA COUNTY (KRON) — KRON4 is looking at the impact new express lanes are having on your commute.

Last year, the toll lanes were added to part of Interstate 580 in the East Bay.

It is basically a car pool lane but anyone can pay to drive on it.

More of these lanes are being built.

On Friday night, KRON4’s Philippe Djegal shows us the effect they are having on drive times.

Watch the above vide to see Philippe’s full in-depth report.
