Here's how much drivers might pay for tolls on future twinned highways

Transportation Department officials are taking the show on the road beginning Tuesday to gauge public support for using tolls to twin more highways.

Department officials say the 304 kilometres in question would cost about $2.2 billion, with half of the funding coming from tolls to be collected over 30 years and the rest being split between the provincial and federal governments.

The department is expected to have final information to present to the government before the end of the year for decisions on how many, if any, projects to complete.

While the information in the presentations includes a possible toll range for each of the stretches of road, the upper end is what would be required to cover half the total cost.
