If you’ve been downtown, midtown or anywhere near the trestle site recently, the sound of pile driving will be very familiar to you by now. But UP’s Mark Davis has good news. 

"We’ll work to finish up the pile driving by Thursday which I know will be a relief to several in the neighborhoods around the area." 

Crews finished work on the trestle’s main track number one early Tuesday morning, much earlier than expected. 

"Extremely far ahead of schedule. I think we were very fortunate for several reasons. Our suppliers had the required amount of material that we needed."

Freight trains are rolling across the new track and Amtrak says it’ll resume service on its Capitol Corridor service this weekend. UP’s Mark Davis says work crews expect to finish the second track early next week.

Investigators are still trying to figure out why the original wooden bridge burned down. And a report is still pending on just what was in the thick plume of smoke that accompanied the fire.
