This bridge has the appearance of an arch bridge, although it is not really an arch bridge. It is the same design as the Derby Street Bridge, but with false arches added to it. The arches were likely added to the Trowbridge Road Bridge because it is a taller bridge They do not appear to play a large structural role, but may help stabilize the taller support system. The bridge is composed of seven spans, supported by concrete piers and seated on concrete abutments. Each span is 33 feet in length yielding a total bridge length of 231 feet. The bridge was constructed in 1930 but not completed until 1931.

The arches on the bridge add a striking beauty to the bridge that is refreshingly different. Most multi-span arch bridges have a shallower arch shape, and so the tall arches of this bridge are quite unusual looking. Triangles embossed on the corners of the arches add accent to the bridge. Railings are a design that features inset rectangles. The railings on the Trowbridge Road Bridge are spalling, and a lack of maintenance and preservation is apparent, and is most disappointing. The Derby Street Bridge has in contrast been painted and was in overall better shape as a result.

There is a private drive sign posted as you turned off of Kensington Road onto Trowbridge Road. Also, it had a newish-looking sign actually naming the road "Trowbridge Court." It would appear that the people that live in this area want to make themselves feel more like a gated community. The legality of the private drive signs is unclear, since this road appears to be maintained by the city (and thus funded through public dollars) and therefore should be considered open to the public. This is a beautiful historic bridge featuring rare design, and associated with am important event in southeastern Michigan history and every effort should be made to preserve this bridge and make it accessible and inviting to the public. In particular, a viewing platform and perhaps a walking trail of some sort should be installed near the bridge to allow people to easily and safely view the beautiful arches of the structure.
