Toledo Girders

Demolition, Blasting

Project Overview

The DiSalle Memorial bridge is a steel deck girder bridge that spans over the Maumee river on Interstate 75. Built in 1963, the bridge is 3,401.1 feet long, with a deck width of 97.4 feet. The length of the largest span is 166 feet. The replacement of the I-75 DiSalle Memorial bridge is part of the I-75 widening and reconstruction project in Lucas and Wood counties.

This project entailed the blasting of 8’ steel I beam girders in phase 1. These beam girders were approximately 920’ in length on the North and Southbound lanes of I-75 spanning half of the Maumee river. Phase II was completed in August 2022 with the blasting of an additional 800′ of steel I beam girders.

Due to the traffic constraints on I-75, the blasting took place at night. The joint effort, between the contractor and the blasting crew, resulted in a flawless blast of the girder spans occurring without incident.
