The MN-24 bridge at Clearwater is the second of two bridges that act as a
quick connection between US-10 and I-94, both of which paralleled the great
river. This bridge is relatively high off of the water, despite not
having river navigation traffic to worry about. The reason is that the
river banks on the south (west) side of the river are rather tall. It
is interesting to note that the bridge uses two sizes of steel girders,
and two types of piers. The main river spans used closed in piers and
much taller girders. The riverbank spans use girders that are about
half as tall, and have an open style of pier.
Clearwater had a ferry crossing at this location as early as 1856. It is
noted as being the longest operating ferry on the entire Mississippi.
In 1897, a freak rainstorm dropped 14 inches of rain in 4 hours. This
resulted in the destruction of the Clearwater mill dam and railroad bridge.
The Clearwater Bridge is scheduled for replacement in 2015. The project
will involve building a new 4-lane river crossing and freeway connection
to I-94.
