Barry County bypassed this historic truss bridge with a modern structure and restored the historic bridge, creating an attractive park around it. They also had an official Michigan Historic Site plaque put up. This represents a pleasing solution to maintaining an efficient road system, retaining structures with significant historic value, and also creating a park for residents and visitors to enjoy. With this solution, everyone came out ahead. Barry County sets a good example for future bridge preservation projects elsewhere.
This bridge is a Pratt through truss with pinned connections. The bridge is composed of eight panels. An unusual characteristic of the bridge is that the portal bracing is identical to the sway bracing. The design of the bracing is an a-frame design. V-lacing is present on the bridge under the top chord and end post as well as on the vertical members. The deck is wooden, and while the deck The abutments are stone, and appear to have been patched as part of the restoration.
According to MDOT's description, which was from before the bridge was restored, there are lattice guardrails on the bridge. Those were unfortunately removed when the bridge was rehabilitated. A couple panels of the lattice guardrails were reused as gates for this bridge. On the other hand, the modern railings placed on the bridge are not as detrimental to the historic appearance of the bridge as railings placed on many other restored truss bridges. However, there was no reason to strip the original railings off of the bridge. The Beyer Road Bridge has modern safety railings placed on the bridge, but the lattice railings were also left on behind the new ones.

Statement of Significance
The McKeown Road Bridge is a
well-preserved example of a Pratt through truss bridge, once a common,
but now rapidly vanishing means of providing transportation over rivers
in the early twentieth century. The bridge is the only steel truss
bridge remaining in Barry County. Despite the area's history as a bridge
site, no bridge was then standing at the time the existing bridge was
proposed in 1902 to 1903. McKeown Road Bridge received its current,
official name during the 1930s when electric companies extended their
services to rural areas and developed a system of naming rural roads to
aid in servicing lines and billing customers. The road and bridge
received their name from C. J. McKeown, a local farmer, who owned the
former Sponable farm on the east side of the road north of the
