In order to meet the Peoria, IL metro area’s transportation needs, the eastbound McClugage Bridge over the Illinois River will be removed and replaced with a new structure. The existing truss bridge is 4745 feet long and 33’-2” wide carrying the EB traffic. The new 4,761-foot bridge is constructed of (22) steel plate girder spans varying in length from 98’ to 222’, along with a 652’ tied-arch span over the main navigation channel.
Westbrook played a vital role in the construction engineering for McClugage Bridge over the Illinois River by designing the cofferdams to facilitate the pier construction, as well as re-design of the proposed coffercells, to increase efficiency on the project. Additionally, Westbrook designed the trestle, trestle transitions, and a unique bent design at the pier “fingers” to facilitate construction of the new bridge. The trestle was rated for a 330-ton crane.
Westbrook also provided the structure removal design and plans for the existing ramp E, which consisted of a variety of girder types, including curved 6’ tall steel plate girders over the Tazewell & Peoria Railroad and 12’ tall steel plate girders over the river.
