“Utah legislators raised questions Wednesday about a proposal to double the tolls on Interstate 15 express lanes — saying they may need to be even higher to cut congestion. Alternatively, they raised the prospect of requiring carpools to have three people instead of two for free use of express lanes.

State highway officials last month proposed doubling the flexible tolls — upping the $1 maximum per section charge to $2, depending on traffic. The Utah Transportation Commission is considering the plan, and may vote as early as next week.”
