What was the common abbreviation for the railroad by which the Cricket Tunnel and Crest Tunnel were built?
Cricket and Crest Tunnels The Cricket Tunnel and Crest Tunnel are a pair of railroad tunnels in northern Arkansas, near the city of Omaha in Boone County. The Crest Tunnel, at 3500 ft is the longest tunnel in Arkansas, and is its only curved tunnel. Both tunnels were built by the White River Division of the Missouri Pacific Railroad in the early 20th century. The tunnels were listed on the National Register of Historic Places in 2007.
IANR Railroad Underpass The IANR Railroad Underpass is a historic structure located in Cedar Rapids, Iowa, United States. It carried railroad tracks for 24 ft over Ely Road. The railroad probably built this stone arch bridge, which was completed in 1887. This kind of structure became more popular in the late 19th century as a railroad bridge because it was more durable than metal truss bridges, and they "projected a refined and sophisticated image." It features a semi-circular arch, a beltcourse, coursed-ashlar masonry, stepped wing walls that are flared, a parapet with projecting coping, and an elongated keystone with the date "1887" carved on it. The bridge was listed on the National Register of Historic Places in 1998. It now carries the Cedar River Recreation Trail over the street.
