The Ravine Bluffs Development Bridge (also known as the Sylvan Road Bridge), constructed as the entrance to a housing subdivision developed by his friend and attorney Sherman Booth, was one of only two freestanding built bridges designed by Frank Lloyd Wright. Six houses including one for Booth were built in the development, along with three entrance features (sculptures with street lamps and planters) and the Ravine Bluffs Bridge. The entrance features and the bridge were executed in reinforced concrete. Although the bridge was a unique example of Wright's work, many of its elements exemplify the Prairie School style he originated. These include strong horizontal lines, rectilinear geometric massing, planting urns and built-in lighting and seating. The cantilevered sidewalk and innovative use of cast-in-place concrete are other Wright trademarks.

The Frank Lloyd Wright Bridge 

Written by J.R. Manning

This bridge was designed by Frank Lloyd Wright as part of the development of the Ravine Bluffs Subdivision in the Village of Glencoe.

This was one of two bridges, designed by Wright, that were actually built. The other is a simple concrete span that is part of the driveway for the private residence of Edgar J. Kaufmann, built in 1935, in Mill Run, Pennsylvania. The Kaufmann home, better known as "Fallingwater," is part of a heritage preservation area, southeast of Pittsburgh. Information about the residence can be found at the official Fallingwater website.

The importance of the Sylvan Road, or Frank Lloyd Wright Bridge, was recognized by a report of historic bridges from the Illinois Department of Transporation in the late 1980s. The significance of Wright's bridge was noted as such:

Nowhere was an early blend of horizontal lines and function more dramatic than in the bridge designed in 1915 by Frank Lloyd Wright. Built over a ravine in Glencoe near a home of his design, Wright's only bridge combined continuity in the deck with a supporting frame of slender members. Replaced in 1985, the new bridge is outwardly an exact replica of the original structure but internally incorporates state of the art reinforcement techniques. The 1915 structure was on the National Register.

The bridge was listed on the National Register of Historic Places in 1978. The Site number is 78001137. According to HAER, because the original bridge was demolished and replicated, but not restored, it was removed from the NRHP listings. However, as of this writing, the bridge still appears in the database.

If frank had built more bridges I wonder what they'd look like? Dude was one of the best architects of all time and everything he touched was gold... We can only imagine.

If the existing bridge is a replacement it looks true to the original.
