The Shade-Lohmann Bridges area two very large parallel span steel
through truss bridges that carry I-474 over the Illinois Waterway
just south of the city of Peoria. Despite its prime location as
a bypass around the busy Peoria area, this is actually the third
most busy river crossing in the Peoria area.
Prior to the upgrade of I-74 through downtown Peoria in 2004 to
2007, trucks were requested to stay off of I-74 and use the I-474
bypass instead. The I-474 bridge was rehabilitated in a project
that completed in 2002. The floor deck systems on both bridges
experienced cracking problems and had to be replaced. In addition,
many of the rivets used on the bridge had to be replaced.
The bridges are named after J. Norman Shade and Martin B. Lohmann.
Shade was the mayor of Pekin from 1942 to 1945 and was elected to
the Illinois state House of Representatives. Lohmann was elected
to the Illinois state House of Representatives in 1923, and to the
Illinois state Senate in 1932. He served in the Senate until 1953.
