The Lincoln Highway in Greene County, Iowa is a multiple property submission to the National Register of Historic Places, which was approved on March 29, 1993.

It includes five individual listings and five historic districts located in Greene County, Iowa, United States.

Carl Fisher was an American automotive and real estate entrepreneur who conceived the Lincoln Highway in 1912, and helped to develop it.

[2] There were no particularly good options to cross Iowa, but the Lincoln Highway Association wanted a direct route between Chicago and Omaha.

It covered 358 miles (576 km) of dirt and gravel roads that began in Clinton and traveled west to Council Bluffs.

[4] Rural roads in Iowa were notorious for their poor condition, and when it rained the mud made them even worse.

The chosen route paralleled the Chicago Northwestern Railroad tracks as they followed the driest and least hilly terrain in the state.

The citizens of the county worked to raise funds to promote and improve the Lincoln Highway through their territory.

This was done as highway design and engineering standards evolved so that curves were straightened, hills were graded, and rail crossings were avoided.

They are composed of a 28-inch (71 cm) octagon shaped post and a rectangular top that are cast in one piece.

[6] A nearly 4-inch (10 cm) medallion of Abraham Lincoln is embedded in the front side of the rectangular top.

They were placed in designated spots about 1 mile (1.6 km) apart by local Boy Scout troops in 1928.

Albert Head, an early promoter of the highway who made significant monetary contributions to its development.

Originally, the highway was designated to be a mile south along the Chicago Northwestern tracks, but the Greene and Boone County segments would not align.

In 1920 a sizable contingent of residents from Grand Junction petitioned to have the route shifted back to the south.

It runs across 2.4 miles (3.9 km) of relatively level farm land from a curve east of Buttrick's Creek to Iowa Highway 144 just south of Grand Junction.

[12] A jog in the road was straightened in 1920, and this whole stretch of highway was paved with concrete in 1924 by Empire Construction Company of Des Moines.

There are six contributing resources to this historic district, all structures: the roadway itself, the road drainage system, and four culverts.

Construction plans from 1923 show that the culverts and half of the drainage system were in place when the highway was paved.

Each intake is a conical-shaped cast iron grate that covers a subsurface concrete cylinder.

[13] The new alignment required a new roadway to be built, and it eliminated all railroad crossings on this part of the highway.

The town section passes through the central business district on the west and a residential area on the east.

The rural section passes along the railroad tracks and under the US 30 overpass before it connects with the newer highway.

The object is a Lincoln Highway Marker that stands in front of the Grand Junction city hall.

It includes Danger Hill where the grade was reduced considerably in 1920 and a jog in the highway was replaced with a curve.

Marsh Engineering Company of Des Moines constructed the bridge that was designed by the Iowa Highway Commission.

It is one of the earliest arch bridges still standing in Iowa, and one of the first designed by the state highway commission.

A partially buried concrete driveway culvert is the other structure, and a 0.1-mile (0.16 km) section of the abandoned dirt roadway is the site.

[16] The structures include the 4.35 miles (7.00 km) of roadway, the road drainage system, eight culverts, and a skew I-beam bridge.

He had these identical markers erected in 1926 as memorials to Abraham Lincoln, whom he considered "one of our greatest citizens.
