HARRISBURG, Pa. -

The likelihood of a deal on transportation funding remains unclear after a lengthy negotiation by Pennsylvania's highest ranking legislative leaders ended inconclusively.

The closed-door, two-hour meeting in the state Capitol on Wednesday involved a set of issues their staffs had produced, and afterward the participants gave few details but said they felt they made progress.

Participants said unresolved issues include where the revenue will come from and whether the state's prevailing wage rules for public works projects will be altered.

The lack of a deal means it's unlikely a bill to fix roads and bridges and support mass transit systems will be considered when lawmakers reconvene next week.

Transportation funding is currently the biggest issue before the General Assembly, and Gov. Tom Corbett has been pushing for a deal.
