Westbound I-70 Mountain Express Lane

I-70 Mountain Express Lanes

The westbound I-70 Mountain Express Lane runs adjacent to the free general purpose lanes from the Veterans Memorial Tunnels to Empire. Similar to the eastbound lane already in use, this 12-mile-long managed lane will feature traffic management systems to improve mobility and provide westbound drivers with a reliable, time-saving option during peak travel periods.

The Westbound I-70 Mountain Express Lane is anticipated to open on July 30, 2021 for testing. No tolls will be collected when the lanes are open during weekends and holidays until testing is complete.

On the I-70 Mountain Express Lane, motorcycles have to pay the toll. Motorcycles must have an ExpressToll account in order to receive the discounted toll rate (Note: motorcycles do not need a physical ExpressToll pass as long as the motorcycle license plate has been added to an ExpressToll account). Motorcycles without an ExpressToll account will be charged the higher License Plate Toll (LPT) toll rate.
