James A. Evans

James Armstrong Evans (1827–1887) was a British-born civil engineer who was part of the effort to build the Union Pacific railroad to Promontory Point, Utah in 1869. Evans was present at the Golden spike ceremony on May 10, 1869, connecting the Central Pacific and Union Pacific railroads at Promontory Summit, Utah Territory. Evans was also in the Russell photograph of the same date

Early life and career
Evans was born on February 3, 1827, in Dover, England. His brother John A. Evans, jr. born in 1852 in Pennsylvania, was also a civil engineer.

In 1872, Evans then living in San Diego, California married Jessie Hunt Henriques (1846–1930) in Ann Arbor, Michigan, a descendant of Edward Howell. They had one child, Percy Henriques Evans (1873–1964).

Union Pacific Railroad
Evans was a division engineer and superintendent of construction in the building of the first transcontinental railway, the Union Pacific Railroad (UPRR) for 1863 thru 1869. In the summer of 1863, UPRR president Thomas C. Durant hired Evans along with J.E. House, Samuel B Reed, Percy T Brown and Ogden Edwards for conducting engineering surveys for a possible route to Salt Lake, Utah. Evans was responsible for the Green River to the eastern base of the Black Hills (now known as the Laramie Mountains) segment of the proposed route, a distance of almost 400 miles thru present-day Rawlins, Medicine Bow, Laramie and Cheyenne, Wyoming. The main challenge for Evans was crossing the continental divide between the latter two cities.

In 1867, Evans had a survey party with an engineering assistant named L. L. Hills, working just east of Cheyenne was killed by a band of Arapaho on June 18, 1867. Percy T. Browne ("P. T. Browne") was shot by a band of Sioux warriors and died at LaClede Station also in June 1867.

Evans also worked on the Texas & Pacific Railroad, the Denver, South Park and Pacific Railroad, and other western railroad lines.

Legacy
Several landmarks are named for Evans.
 * Evans Pass (now known as Sherman, Wyoming)
 * In 1869, Albert D. Richardson then a correspondent for the New York Tribune wrote that at that time, Evans pass was
 * "...the highest railway point in the world -- eight thousand two hundred and forty feet above the sea. Still, it is not the backbone of the Rocky Mountains, but only of the (Laramie mountains), an outlying eastern range. The continental divide is two hundred miles further west and one thousand feet lower. ... Evan's Pass ... bears the name of its discoverer. ... The pass is in no sense a gorge or canyon -- but looks, topographically, like a vast rolling prairie disfigured by rocks and reached by a gentle ascent. Nor are the distant mountains on the north and south such slender peaks and pyramids as fanciful artists depict, but only low, irregular, broken ridges."
