The Murray Baker Bridge was built to carry I-74 across the Illinois River
near downtown, Peoria. The Interstate highway was known for having a
lot of substandard entrances and exits. In fact, it was dangerous enough
that trucks were eventually requested to avoid the highway in favor of
I-474. A project to rehabilitate I-74 ran during the mid-2000s. The
signature accomplishment of this project was to amputate 180 feet from
the north end of the bridge to make room to add entrance and exit ramps
for an interchange near the riverfront. This feat had never been attempted
before on a major truss bridge. The resulting I-74 highway is a dramatic
improvement from the old highway.
The bridge itself is a landmark structure in the Peoria area. It is
a very large truss structure, world class in length. It features
four interior piers, which means that it has four peaks in the
structure. Despite being such a large structure, it only has room for
4 lanes of traffic without shoulders. This puts the bridge in a class
where it is not officially up to Interstate highway standards.
Murray Baker is an Illinois native who was instrumental in getting
the two companies (Holt and C.L. Best) who later merged to form
Caterpillar to move to Peoria. Baker became Vice President and
Director of Sales for Caterpillar and later served on the Board of
Directors.
