Located in Logan, this multiple span girder bridge is the ninth crossing of the Boyer River.
The original bridge here was a three span through girder bridge, built in 1899. However, this bridge was upgraded several times.
The current bridge is built of three distinct spans. The southern span was built in 1928 by American Bridge Company, and installed here in 1957. This span was relocated from an unknown location. The center span was built in 1899 by American Bridge Works, and either was shorted by three feet or moved from elsewhere, likely along this line. The north span was also built in 1899, and is believed to be original to this location.
The substructures for this bridge are all concrete. The north (railroad east) abutment is original to the 1899 bridge, while the north pier was rebuilt in 1950, the south pier in 1953 and the south abutment in 1957.
It is not unusual for a Boyer River Bridge on this line to have such an unusual series of spans. When the Boyer River was channelized, many crossings were either filled or rebuilt. The filled crossings oftentimes seem to have donated spans to other locations.
Overall, the bridge is in fair to good condition. The superstructure appears to be healthy, as does the substructure. The biggest issue is the south abutment, which has bare pilings exposed.
The author has ranked this bridge as being locally significant, due to the common design.
