HOUSTON -

The Houston area’s fourth highest occupancy toll opens Monday.

Transportation officials say the 290 HOT lane opens Monday morning. That means you can drive the full 13.5-mile stretch of the current 290 HOV lane, even if you’re by yourself; but, it will cost you.

“If you're an HOV lane, you can continue to use the lane free, but if you're a single occupant driver, you can use it during certain hours by paying a toll,” said Tom Lambert, interim president and CEO of Metro.

The toll will cost drivers between $1 and $5, depending on the time of day and the flow of traffic.

“The greater the demand, the more you are going to have to pay,” said Lambert.

Metro says if traffic is extremely heavy, it may close the HOT lanes and only allow HOV drivers on the lanes.

How will you know how much you’re commute will cost?

Metro says pay attention to the signs.

“There's a lot of advanced signage to let you know when you can use it,” said Lambert. “There's a price on what it will cost when you use it.”
