A major expansion of the MnPASS electronic toll system advanced Tuesday in the state Senate despite some legislators' objections to charging more motorists to drive in the fast lanes.
The measure would widen 4 miles of Interstate 35E in St. Paul and dedicate a lane in each direction to MnPASS tolls, carpools and buses during rush hours.
The expansion is backed by Sen. Joe Gimse, R-Willmar, chairman of the Senate Transportation Committee, as a less costly way to reduce traffic jams than more extensive road building.
"In these times of tight budgets, we need all the tools we can get," Gimse said.
But other Republicans opposed the tolls.
"I'm just not sure why we're charging people to use those lanes," said Sen. John Howe, R-Red Wing.
A divided Transportation Committee passed the measure after four Republicans failed to approve widening the stretch of 35E without the toll lanes.
The Minnesota Department of Transportation told legislators on Tuesday that electronic tolling is needed because any added general-purpose lanes will become congested soon after they're built.
