The bridge’s spider population contains many different varieties.

A naturalist said that the spider infestation actually is a good sign. After the Scioto River was narrowed to make room for a park with hundreds of trees and thousands of plants, the insect population has thrived.

The bright lights on the bridge attract many kinds of flying insects.

The spiders are just following the food trail.
