HUMMINGBIRDS: Dan Hasney of Wilcox called to report that he just spotted a hummingbird, and he wondered if anyone else has seen hummingbirds recently.

“This is pretty late” for the birds, he explained.

Readers, and sightings?

DEMOLITION: When we saw this bridge demolition photo from the Pennsylvania Department of Transportation, we had to pass it along.

This is the old Hunter Station Bridge on Route 62 that crosses the Allegheny River in Tionesta Township, Forest County.

Or, it was.

This is a photo of PennDOT demolishing the remaining superstructure on Wednesday using 160 shaped explosive charges.

The agency put a lot of work preparing the river for the project.

“PennDOT’s northwest region has been preparing for the environmental impact of the bridge construction and demolition over the past 10 years by removing approximately 155,000 mussels from the Allegheny River at the construction area under the bridge and sending them to other waterways in Pennsylvania and six other states,” a statement from the agency explained.

We wonder what that process was like.

“Approximately 105,000 of those mussels were federally listed threatened and endangered species,” PennDOT reported. “The effort is thought to be the largest translocation of threatened and endangered species ever undertaken in North America.”
