The I-70 Mountain Express Lanes help improve your mountain travel, but they operate a bit differently than regular Express Lanes.

Unlike other Express Lanes, all vehicles must pay a toll, without exception for HOV3+ or motorcycles. Oversized vehicles, such as trucks and trailers, are not permitted. When closed, these lanes are used as shoulders for emergencies only.

When it comes to weaving, the same rules apply: only enter and exit an open express lane through the dashed line. Crossing the solid line poses a safety risk and will result in fines.

As narrow shoulder lanes, federal regulations limit how often Mountain Express Lanes can be open. Look out for signage or visit ColoradoExpressLanes.com for general operating hours and additional information.

You can also sign up for the new Mountain Express Lanes text alert service to receive regular updates on unplanned openings, closures or delays. Sign up now by texting “xpresslanes” to 2100.
