History
Dunlap was platted in 1867, and it was incorporated in 1871. The city was named for George L. Dunlap, General Superintendent of the Chicago & North Western railroad.
The location of Dunlap was within the final 50 miles of the railroad's Council Bluffs goal, connecting with the Union Pacific's transcontinental railroad building from Omaha. By January 1867, the engineering had been completed to Council Bluffs and by April 30 the first trains would be able to run all the way through, making this the first uninterrupted rail connection with the East. So with the concurrence of John B. Turner, former Pres. and Director of the C&NW, on Feb. 13, 1867 George L. Dunlap wrote Isaac B Howe, Supt. of the Iowa Div.: "(Dunlap is)...the proper point for terminus of the Division, ...locating a town there and establishing comfortable homes for our men, thereby attaching them to the Co.'s interest and increasing their efficiency."
Dunlap's historic Independent Order of Odd Fellows Hall was added to the National Register of Historic Places in June 2011.
