The Northwest Corridor Express Lanes have been open for more than a month, and state transportation officials want your feedback on how they're working. The Atlanta Journal-Constitution is also interested in your thoughts.

The new toll lanes stretch 30 miles along I-75 and I-575 in Cobb and Cherokee counties. The lanes are reversible, carrying traffic into Atlanta in the morning and out of town in the afternoon.

The lanes allow motorists to bypass heavy traffic on a congested stretch of highway – if they're willing to pay by the mile. Early results show thousands of commuters are taking advantage – motorists took 108,850 trips during the lanes' first full week of operation, according to the State Road and Tollway Authority.

Now SRTA wants to know: How much time have the Northwest Corridor Express Lanes saved you? How far do you usually travel in the lanes? Are the current operating hours beneficial to your commute?

These and other questions are part of an online customer satisfaction survey. You can take the survey here.

Meanwhile, the AJC is also interested in your thoughts on the new express lanes. Are they a regular lifesaver on your morning or afternoon commute? An occasional way to beat traffic when you’re running late? An abomination that you’ll never use?
