A tractor-trailer was seen driving past a WTAE camera on Tuesday. PennDOT acknowledged that it would have been a violation if it had been caught.

Pittsburgh's Action News 4 checked out both ends of the span on Tuesday and didn't see any enforcement of the weight limit.

Violators can be fined up to $10,000.

"We've contacted Pennsylvania State Police, and they will be anticipating setting up weight stations to enforce that," PennDOT District Executive Dan Cessna said at a news conference on Monday.

Despite the lack of enforcement that WTAE saw, PennDOT said there were "stationary checkpoints and roving patrol" in place Tuesday, and it said those efforts would continue to be conducted.

As of Tuesday afternoon, after the inquiries made by Pittsburgh's Action News 4, we did see state police enforcement on the bridge.

PennDOT spokesman Steve Cowan said state and city police, and possibly Allegheny County police, will be involved in enforcement.

The bridge was closed for more than three weeks after a fire damaged a critical steel beam. Temporary repairs were successful enough to reopen the span with a lower weight limit until permanent repairs can be made.

"Crews will work to add steel to strengthen one truss chord. When the repair is complete, the bridge will be placed under the pre-closure weight limit of 30 tons," PennDOT said in a written statement. "Once the rehabilitation project is complete in 2018, it is anticipated that the bridge will have a 40-ton weight limit."
