The curved t-beam is a historic structure type as it utilizes a design no longer applied in modern bridge engineering, and also are among the last bridges to be built with attention paid to aesthetic railings and superstructure. However, particularly on I-94, there are a number of this structure type remaining, and as such it makes sense to eliminate some from inclusion in a historic bridge inventory or this website. In most cases, this website only includes curved t-beams that retain unmodified original railings. The attractive railings, a standard of the period, play a major role in defining the appearance of this structure type. Also, very few curved t-beams retain unmodified original railings, making those that retain them stand out of the crowd. However, the 27 Mile Road Bridge is a bridge that has those railings, but modern Armco railings have been bolted on in front of them. This is a process that MDOT has been doing slowly to the remaining curved t-beams with unmodified railings. Despite these modifications, the 27 Mile Road Bridge still merits inclusion because of its heavy skew, approximately 45 degrees. As such, the beams are notably longer and deeper. Compare this bridge to the 23 Mile Road Bridge. In addition, the bridge has an interesting appearance that is associated with the illusions that are created by the skew as the eye looks at the shape of the arch from certain angles. Most importantly, the bridge is significant as a longer, skewed example of this structure type. Even with modified railings, this bridge remains an important part of Michigan's transportation heritage.
