Gov. Tom Wolf’s administration has picked a group of companies to manage construction on as many as nine major interstate bridges in Pennsylvania — upgrades on the aging spans that are to be paid for by tolls under the administration’s current plan. Wolf’s push for tolling comes as states increasingly look to user fees to make up for declining gas tax revenue. However, it has spurred opposition from some communities and Republican lawmakers, who say it will be costly to locals and businesses and create congestion. It also comes amid rising gas prices. Wolf’s Department of Transportation selected the group from among three finalists, but also said Wednesday that it has not decided which of the nine bridges it will toll.
