CBS News Denver reports that the true effect of CDOT’s decision to raise the vehicle occupancy requirement on I-25 and US 36 Express Lanes to HOV-3 won’t be known until the winter vacation period ends next week. The network adds, “The I-70 Mountain Express Lanes as well as the new C-470 Express Lanes will be toll-only and not have an HOV option. Current HOV lanes which do not have a toll like the ones on [US 85/Santa Fe Drive] will remain HOV 2+ and will not require a transponder to ride for free.”
